I discovered a Fossil on the Seaside and Questioned
Up to date on March 22, 2017 Kathi moreContact Writer Discovering Widespread Fossils on Great Lakes Beaches
A favorite previous time for many is combing the beaches for interesting objects the surf washes in. Whether or not you are strolling alongside the shoreline of the ocean or the nice Lakes within the USA, your imagination is on excessive alert to pick something up you just cannot move by! Suddenly, something catches your eye! However, it isn’t driftwood or seaside glass and even a reasonably rock. You could not know precisely why, however you suspect you found one thing that was once a residing creature.
Has this ever occurred to you A deep sense of curiosity and childlike imagination drives us to find out what we may have picked up along our saltwater or freshwater shorelines. Having collected fairly just a few samples from Lake Michigan’s shoreline, myself, I lastly determined someday to satisfy my nagging curiosity and adopted by way of with a rewarding investigation. The extra I realized about my stony sand-smoothed findings, the extra I wished to know. I questioned what the creatures might have regarded like when alive and the way they survived. I additionally wished to understand how they confirmed up so prevalent alongside the recent water beaches. A while later, after many answered questions, I can truthfully say I take pleasure in a cool passion. Taking issues a step additional, I’ve drawn illustrations of their dwelling beings and began a fossil site. You will discover the hyperlink at the top.
A few of probably the most prevalent fossils discovered alongside the nice Lake’s beaches are crinoids (proven within the photographs to the precise). They’ve been coined with a a number of names because of the animal’s options and by the character of their fossils found all through historical past. One widespread title for them is “Indian Beads”. Native Individuals had been recognized to make necklaces with their damaged up items which resemble the form of beads excellent for stringing. They’ve additionally been known as “Fortunate Stones”! Spotting one takes a eager eye as many of the items are fairly small.
As residing creatures, each circular part was stacked one over the other constructing the animal’s complete framework. They possessed branching arms that sat atop lengthy single stems. They had been sessile creatures, in different phrases, they remained hooked up to the sea ground. Some varieties are recognized to have towered a number of meters in length. Their free construction resulted within the dwelling organism’s beautifully colored and flower like look which granted them the nickname of “Sea Lilies”. They captured tiny meals particles passing by on ocean currents with their feathery community of arms that functioned like traps. Crinoids match into the phylum of Echinoderm, which means spiny pores and skin, and are cousins of starfish, sea urchins and feather stars.
Sea lily crinoid’s lengthy history began in the course of the Ordovician Interval round 500 million years in the past, though most fossils are from the Mississipian Interval round 345 mya and are preserved in limestone. In the present day there are far fewer species and most lack the long meandering stem frequent in Paleozoic varieties.
Within the course my investigation, I had typically puzzled why so many crinoid fossils ended up along the great Lakes; significantly by the fact that they had thrived in saltwater environments. I’ve since realized they are often discovered widespread in North America. A part of the reply to my inquiry is straightforward sufficient to clarify. Throughout their lifetime, much of the world’s continents have been lined underneath warm shallow oceans, together with parts of North America. So how is it their fossils are so widespread close to the massive lakes The reply is as a result stone island aix en provence of ten thousand years in the past when the large glaciers sculpted the deep basins forming the great Lakes, in addition they dug into the deep layers where their Stone Island Outlet stays rested. In the method, they have been deposited the place we now can uncover them and revel of their secrets and techniques, in addition to that of different species from the same period.
One other common beach discover, bryozoans are often referred to as lace corals due to their delicately threaded look, however they aren’t true corals. As a substitute, they’re moss-like animals belonging to the household of Fenestellida for his or her fan-formed, mesh appearance. They stay in tight colonies sculpted by hard, limy, branching constructions. The colony consists of 1000’s of particular person animals referred to as “zooids”. Every particular person zooid lives inside its personal limy tube known as a zooecium. The zooecium are the size of sewing needles. A single zooid begins the colony. A bryozoan colony has been noticed rising from a single zooid to 38,000 in just 5 months. Every further zooid is a clone of the very first one.
Fascinating how they feed, Every zooid has an opening by way of which the animal can lengthen its ring of tentacles referred to as lophophores. Their lophophores seize microscopic plankton from the water passing by. If one zooid stone island aix en provence receives food, it nourishes the neighboring zooids because they’re joined by strands of protoplasm. If solely we people might be extra like them making certain everybody on the planet is fed!
Their fossil report dates again 500 mya with 15,000 recognized species. Today there are about 3,500 living species.
I discovered these clam fossils on the shore of Oval Seashore in Southwestern Michigan. The shell of the darker pattern has been fully changed by minerals and is petrified to stone. Its easy floor is a telltale demonstration of the lake’s sand and water motion. The lighter coloured pattern clearly reveals the hardened muddy sediment that has utterly encrusted its shell.
“Clam” generally is a time period that covers all bivalves. Some clams bury themselves in sand and breathe by extending a tube to the water’s floor. Bivalve oysters and mussels attach themselves to laborious objects and scallops can free swim by flapping their valves collectively. Every kind lack a head and often don’t have any eyes, though scallops are a notable exception. With the usage of two adductor muscles they’ll open and shut their shells tightly. Very fittingly, the phrase “clam” provides rise to the metaphor “to clam up”, which means to cease talking or listening.
Bivalves have occupied Earth as early because the Cambrian Interval 510 million years in the past, however they have been notably considerable through the Devonian Interval round four hundred million years in the past. Their fossils are found in all marine ecosystems and mostly in close to shore environments. In 2007, off the coast of Iceland, a clam was found to be no less than 405 years previous. It was declared the world’s oldest residing creature by North Wales, Bangor College researchers.
No different organisms typify the Age of Invertebrates greater than brachiopods. They’re probably the most plentiful Paleozic fossils, aside from perhaps trilobites. Paleontologists use them thus far rocks and other fossils. Numerous billions accumulated on the ocean flooring with over 30,000 types. Right now there are far fewer species, solely about 300 which stay principally in cold water, deep ocean environments.
Brachiopods appear like clams but are very completely different inside. To inform them apart, clams have uneven formed shells, however each prime and backside halves are similar. Brachiopods are symmetrical at a look, however the underside shell is smaller. Brachiopods are commonly called “lampshells” due to their similarity in form to a Roman oil lamp.
They live in communities connected to objects by a muscular foot known as a pedicle. They pressure water in and out of their shells filtering microorganisms with their lophophores, a crown of tentacles.
During the Devonian time slot, over 350 million years in the past, Michigan was lined by a shallow saltwater sea. That is the place mass colonies of corals known as Hexagonaria, percarinata, generally often known as Petoskey Stones, thrived and flourished. The saltwater seascape will need to have been lit up with a quilt-work of colours by the mass colonies. Unfortunately, they turned extinct at the top of the Permian Period’s mass extinction.
The identify “Petoskey” originated from an Ottawa fur-trader chief named Petosegay. A northern Michigan metropolis was named after him, solely the identify was modified to Petoskey. Due to their abundance alongside Michigan shorelines, especially within the northern areas close to Petoskey, Governor George Romney signed a bill in 1965 that made the Petoskey Stone the official state stone.
When observing one of many fossils, every coral hexagon construction, seen to the attention, held a single animal which opened a mouth to expose tentacles. The tentacles took in meals and had been also used to sting any organism or different corallite that got here too shut. Calcite, silica and different minerals changed the unique corallite exoskeleton.
An extinct order of coral referred to as tabulate corals additionally formed reefs and lived in heat shallow waters throughout the identical interval because the Petoskey Stone corals. They have been the favosite corals. The tabulae (horizontal internal layers) were built outward because the organism grew. These layers can clearly be seen in the picture to the proper. The favosites will also be recognized by the honeycomb sample on the exterior of their fossilized stays.
Hope you’ve got loved my fossil discoveries. Subsequent time you go to the seaside, keep your eyes open for a fossil discovery of your personal. You are welcome to make use of my hub or go to my fossil weblog to assist make an identification!

Good introduction to fossils and fossil trying to find rookies Kathi.
I like the road:
‘A deep sense of curiosity and childlike imagination drives a few of us to search out out what we picked up alongside the freshwater shoreline.’
That is the unlucky level I feel. For some motive, as individuals develop out of childhood too many lose their childhood fascination for such things as fossils, in addition to different wonders like the creatures which reside in a pond, or the stars to be seen in the evening sky. That is unhappy – if solely everybody might keep that sense of curiosity and imagination as they develop up – the world could be a way more wondrous place for all – adults, in addition to kids.
I hope some at the least feel impressed as they walk along a shoreline or beside a cliff face, to show over a number of stones and see what they’ll discover. Alun

Sure, Fossillady, I did take pleasure in this. This has been an afternoon of studying. I’ve learn so many attention-grabbing articles this afternoon and this one is certainly one I will remember. I had no idea. It is amazing how much there is to learn about fossils.
Sending many Angels your approach this afternoon. 🙂 ps

Hey this is so cool i just purchased my first fossil and wana speak with people abot this stuff . somebody text me haha
Hey Micky, good to see you, sorry so late as I have been so busy lately with new jobs and all! I miss the regular contact with all my hubber associates! Thank you for the great comment, you’re very variety to say so! Hope every thing is nice with you! Hugs my pal

Your hubs are so pretty! Thank you dear Fossillady!
Ha, What do you know, I’m a geo-jokster and don’t even know it…hee
Ha fossillady something new…LOL and were talking about fossil Ha that’s a great geo-joke…
Extremely pleased with this discussion Tom and Birdy, learned something new!!!!!
I guess it is like a tree with the circles. Fascinating.
I’m fairly positive the accretion traces on the highest of a clam will reveal its age-just like the rings on a tree the clam gets bigger and another ring is added-

I will talk fossils with you any day. I’m in contact with each sides of my mind! Typically I shock myself, lol.
“In 2007, off the coast of Iceland, a clam was found to be not less than 405 years old. It was declared the world’s oldest living creature by North Wales, Bangor University researchers.” How do they know this and the place is the clam at now How does one decide the age of a clam that has seen centuries move Oh, I feel a poem simply got here to thoughts. Each sides of that brain are reacting at the same time.
Thanks for a great and well researched Hub.
Very kind of you Janet! I had by no means labored with pastels earlier than so there’s numerous room for enchancment, they’re principally focused for children! Next time you are on the seaside or in nature I hope you can acknowledge some of these fossils!

Very fascinating hub,Fossillady !Very informative and I really like the artwork! It is superior.I by no means knew some of these were fossils! Well,I positive learned one thing tonight!
Thanks for sharing both info and artwork…good combo!
i do know its kinda humorous I at all times preferred Ross too and my spouse would at all times take a look at me when he would say one thing geological…
don’t fret- submit a fossily hub i am going to learn it…
ya obtained one fan…its a begin
I know what you imply, no person wants to speak about fossils with me both. Jogs my memory of Ross on Mates. He at all times needs to share his details about fossils and the others will not have something to do with it!lol
I’m simply glad to speak fossils ith somebody- my kids likem but.. even they tire of looking fast
Great recommendation Tom, Very much appreciated!
When cleansing crinoids- ya gotta know what kinda rock is clinging to them- relies on the rock sort you findem in round here it iseasily found in shale i usually rtry to clip off- the best i can with toe nail clippers – be careful- then i will use a reasonably dilute HCL resolution between .1 and .25 dilute-use a “smooth wire brush” possibly nylon brush-ajust hcl to rockhardness- at all times use acid in wellventilated area use safety glasses and neoprene or nitrile gloves- sandstone embeds- could be picked off the crinoids and a final acid wash
Hi Workingmom, Good to see you right here! I wish I had advise for cleansing fossils, I’d think so long as you don’t use something too harsh,it will be okay!
It sounds like it’s not all that hard for you to find the crinoids where you are! I get so excited whenever I can spot one! lol…take care!

Love this hub! I was actually eager about writing a hub about crinoid beads (actually about utilizing them to create jewellery, since I try this). My husband is an amateur archaeologist (aka rock hound), and he began taking me with him when we first started dating. I didn’t care much about finding the arrowheads that he was hunting, but I fell in love with the beads! We were just down in Monroe Co.KY, and located fairly just a few inside a couple of minutes by a few of the various creeks. By the way in which, do you know a good method for cleaning fossils I need to clean those beads if I’m going to make jewellery out of them!
Hello Tom,Oh it seems like a rick fossil discover space. I’ve by no means discovered a trilobite, my husband did once while working on the railroad. I like to find crinoids that are still attach, but it would be even higher to seek out one totally intact! Thanks for stopping by!
We’ve the sme devonian aged fossils close to Lake Erie- that shallow sea was really big when my son went hunting with me he said what are all these nuts and washers doing here-on the ground of course we have been in a crinoid wealthy space. There have been a ton of Brac’s s properly-then we discovered some smaller trilobite halves and a had an incredible time diggin the dirt and shale shards He kept pulling up shale and asking what it was then he gave me one with a Trilobite trace fossil (imprint) it was actually a very good one
Hello WillStarr, You made your youngsters really feel very particular that day! An exquisite fatherly factor to say. I would love to go to Kentucky and take a look at the shale bank. Kentucky has several fossil websites I’ve read about! I acknowledge you from different hubs and that i see you are now following me, proper again at ya!
WillStarr 6 years in the past from Phoenix, Arizona
The Kentucky farm the place we lived for a number of years had a shale bank on one facet of a stream that was loaded with fossils. My youngsters were fascinated once i told them they have been wanting on the beginnings of life on Earth, and that their eyes have been the primary human eyes to ever see what they’d discovered.
Nice, I’m glad you made a brand new discovery, I hope you find plenty of fossils! It actually is fun when you find one! It’s gratifying later when you’ll be able to establish it!

Wowwee! Nice hub. I reside in Lengthy Island New York, the place there are miles and miles of beaches. I never knew among the issues I used to be looking at could be fossils. When the weather is hotter I’ll revisit your hub to look and study extra. Thanks for educating me. Rated up and superior.
My jaw dropped whenever you talked about coelacanth fish that was found! I’ve read that too! I would love to come there and fossil hunt. I’ve by no means been throughout the ocean. Hope to try this earlier than my day comes round!
Nell Rose 6 years in the past from England
Hello, you must come over to England, you’ll have an important time! lol the last time I went to Lyme Regis, Jurassic coast, they were filming for Tv, and they’d a fossil programme full of all they’d discovered, I’d think about that there are nonetheless a great deal of what we imagine to be extinct animals nonetheless on the market residing in the deep ocean, I remember studying that fishermen found a coelacanth fish still dwelling again in 1933, and that i consider they’ve caught just a few extra since then, so that you by no means know! cheers nell
Well, you have made my day and i hope yours is filled with love and joy! Hugs

As a matter of fact I am engaged on one partly due to your encouragement! It is much appreciated!
..Howdy Kathi – yes I love to walk along my beach in the spring, summer and fall and pick up ‘found objects’ and flotsam and jetsam washed in from the tide especially after a storm or excessive winds but as I speak there is so much snow and ice down there proper now you can’t see anything besides an enormous blanket of white – everywhere you look – I imagine I can have to wait until the spring now to discover anything new and get back to my days of ‘beachcombing’ …….if you have any extra pictures about your days on the seashore or simply round the place you reside it can be good to see you make one other photographic hub on that topic ……

I can not assist however really feel sorry for poor deaf kitty, however I am positive he/she’s in good palms. We’ve got the identical lake impact on the west coast of Michigan attributable to the westerly winds. In reality we’re in a snow belt space. Final couple of years we have had report snowfall over one hundred twenty inches. Do you decide up fossils whenever you stroll the seaside Thanks once more on your assist!

…completely fascinating hub topic you might have written about right here …. I stay on the northern shores of Lake Erie in Ontario, Canada and that i stroll on a regular basis alongside my seashore with my deaf cat (on a leash). I reside a hundred ft away from the lake ……and that i at all times see flotsam and jetsam and located objects that are washed up every day whether or not or not it’s man made or miracles of natures.
By the way in which how is the weather the place you reside
We frequently get what is called lake impact situations due to the winds off the lake.
Once more you’ve got actually executed some great research here in your hub and can be a worthy addition in any classroom!

Very cool hub , I’ve a good friend I’m going to point out this to. They’re in all probability on the seashore right this minute on the west coast accumulating shells as I write this!
