The 2013 National Fossil Day artwork features a variety of marine invertebrates from the Paleozoic Era. Along the seafloor, a eurypterid, also known as a sea scorpion, chases after a soon-to-be meal of trilobites. Click on the tabs below to learn more about the animals featured on the logo, as well as ancient seas and the importance of Paleozoic marine invertebrate fossils. The state fossil of New York is a Silurian eurypterid: Eurypterus remipes (the first eurypterid ever discovered). The name eurypterid is derived from the Greek word for "wide" or "broad" (eurys) and the Greek word for "wing" (pteryx). Trilobites were incredibly diverse marine arthropods which primarily lived on the seafloor and fed on detritus.
Trilobites are now extinct, although they existed throughout the Paleozoic and their fossils are found on every continent.
Three states have trilobites as their official state fossil: Ohio (Isotelus from the Ordovician, Pennsylvania (Phacops rana from the Devonian, and Wisconsin (Calymene celebra from the Ordovician and Siluiran. Trilobites were a spectacularly diverse group of marine invertebrates and the most well-known Paleozoic fossil.
Trilobites are among the oldest Paleozoic marine invertebrates, appearing about 540 million years ago during the Cambrian. The term "trilobite" was derived from Greek words meaning "three-lobed" referring to the three longitudinal (parallel to the body's length) lobes of trilobites. Bryozoans, or "moss animals", are sessile, colonial, marine animals that superficially resemble corals, but are from a completely different phylum.
They are one of the latest-appearing phyla in the fossil record and are still extant today. Bryozoan colonies encrust hard surfaces (even the bottoms of ships!) or form beautiful fronds. Bryozoans appear similar to coral and are primarily sessile (immobile), colonial marine animals. Individual bryozoans, rarely more than a millimeter across, are called "zooids." They live in colonies ranging from a few to a few million zooids. Although they look like modern corals, rugosans are a much more ancient group, going extinct before modern stony corals appear in the fossil record. No rugosan corals are state fossils, but other Paleozoic corals have been selected as the state rock of Michigan (Hexagonaria percarinata, the "Petoskey Stone," of Devonian age) and the state stone of West Virginia (Lithostrotionella, of Mississippian age). Rugose corals, also called "horn corals," are an extinct group of Paleozoic corals that were abundant from the Middle Ordovician through the Late Permian.
Solitary rugosans often were horn-shaped, giving the group its common name, and could reach sizes around three feet in length.
Gastropods (snails) are the most diverse group represented on the National Fossil Day artwork. The fossil record of gastropods extends back to at least the Lower Cambrian and covers every continent and every subsequent period of geologic time.
Although gastropods today inhabit nearly every habitat on earth, the first gastropods were marine. Of all the animals featured on the 2013 artwork, the one you are most likely to run into (well, outside of a rock shop or fossil museum, anyway) is the gastropod, or snail. Although marine snails today have a variety of shell shapes and some complex ornamentation, early Paleozoic gastropods had simple mostly unadorned coiled shells, similar to the snail in the NFD artwork (loosely modeled after the Ordovician and Silurian genus Salpingostoma). Gastros is Greek for "stomach" and poda is Greek for "foot." The term "stomach foot" refers to the appearance that a snail is crawling on its stomach. Throughout the Paleozoic Era, shallow seas covered much of North America, meaning marine invertebrates had extraordinary expanses of habitat. Marine invertebrates are fantastically diverse and immensely important to paleontology and modern society.
Although they don't star in many feature length films, Paleozoic marine invertebrates were swimming, crawling, burrowing, building reefs, attacking prey, filter-feeding, stinging, exploiting new habitats, constructing elaborate shapes and shells, and evolving for hundreds of millions of years before terrestrial animal fossils appeared during the Devonian. Numerous National Fossil Day partner fossil sites and museums are excellent places to learn about the fossils on the 2013 artwork. Overall, Paleozoic marine invertebrates are incredibly common fossils and can be found in just about every natural history museum and rock shop in the country.
Tonight at 10P, National Geographic Channel follows the wild life of Mick Dodge, a quirky character whose unique brand of Zen comes from living off the land and off the grid, in the new series The Legend of Mick Dodge.
He has been called “the Forrest Gump of Middle Earth,” “Tree Beard,” “the Barefoot Sensei,” “the Hobbit” and “Big Foot.” Whatever you call him, Mick lives life by his own unique philosophy.
Mick explains, “My family’s perfected the art of dodging civilizations for hundreds of years. Though he lives far from civilization, Mick’s world is populated by a unique breed of outdoorsmen with names like Sunray, Moss Hopper and Will of Stone. My husband believes this show is just like Animal Planet’s Mermaid show and the infamous Alien Autopsy show.
If Nat Geo had promoted a show about a man who walks the middle path – would you have tuned in?
The Wastelands, the Open-Fenced Lands and the Gated Wilds aren’t they in Middle Earth? Why even put this on TV without a disclaimer that this is someone selling something totally fabracated? If he has no cabin or house and “lives in the woods” i wonder where his dog is most shows? Nat Geo- based on the same framework you are using for The Mick Dodge show, why don t you just follow Bigfoot around in the forrest instead? I agree there is s lot of questionable content and scenes in the show but to suggest NatGeo should cancel it based on that is silly.

Very realistic scene where Dodge made cart wheels out of ready made slices off a log found in a slash pile at an old landing site! Welcome to our inaugural column of Ask Your Weird Animal Questions, where we give you a chance to satiate your curiosity about the wild world. The males, who are much smaller than the females, sniff out a mate and give her the love bite of a lifetime, hanging on until an enzyme fuses his body into hers.
Nilantha Aajeewa of Kalawana, Sri Lanka, wrote in last fall asking for help identifying a reptile after reading about zoologist Ruchira Somaweera and his study of the horned lizards of Sri Lanka.
A lot of species are also determined with sophisticated DNA techniques, like this new species of humpback dolphin that was hiding in plain sight in Australia. Last, as the stunning number of annual new-species discoveries attests, some animals are just plain good at not being seen. While many land animals regenerate body parts, such as deer and their antlers, it does seem that many regenerating animals are aquatic, like sea stars, tunicates, and salamanders. For instance, some aquatic species simply regenerate easily and often like sea stars, while other species may take longer or have more trouble—so we may think of the super-regenerators more often. Guedelhoefer added that aquatic creatures tend to pop up more “simply because more biologists chose to spend their days collecting on the beach rather than digging in the mud,” he says. Progress has been made with creating tooth material that genetically matches human teeth needed for implant. We hear of occasional stories of dolphins saving a swimmer, but we don’t seem to hear about any who take a hapless victim further out to sea. For the anglerfish, if the male ends up morphed into the female, when does the actual “intercourse” begin?

The scene is an idealized representation of a seafloor from the Ordovician Period (between about 485 and 444 million years ago) near what is now Cincinnati, Ohio. The 2011 National Fossil Day artwork featured a fearsome aquatic predator of the Mesozoic.
They were also among the largest arthropods (same phylum as insects, spiders, and crustaceans), getting up to more than eight feet in length.
The front set of appendages are chelicerae that look like (but are not homologous to) scorpion pincers. By the end of the Cambrian, about 50 million years later, they achieved their maximum diversity. However, bryozoans are in a completely different phylum than corals, and the bryozoans were among the last animal phyla to appear in the fossil record. Bryozoans feed on even smaller microorganisms like diatoms via a filter-feeding structure called a "lophophore." They secrete a rigid skeleton of calcium carbonate (limestone) that forms the framework for the colony. They reached their peak diversity during the Devonian and their fossils have been found on every continent except Antarctica. Although none of their soft parts have been preserved, rugose coral polyps were likely similar to modern corals in that they had tentacles (perhaps even with stinging cells) and could capture food floating past.
There are at least 62,000 living species of gastropods and tens of thousands in the fossil record. Maryland's state fossil (Ecphora gardnerae gardnerae) is a predatory marine snail from the Cenozoic Era. Gastropods today are found in just about every aquatic and terrestrial habitat from equator to pole. The red star indicates the location of the idealized seafloor featured in the 2013 artwork about 450 million years ago (mya).
Indeed their fossils are found across the continent and span hundreds of millions of years of geologic time.
North America was near the equator during much of the Paleozoic, meaning many of the shallow seas were warm and teeming with life. Because many species of marine invertebrates were widespread and abundant, but only lived for a relatively short (geologically-speaking) period of time, they make excellent index fossils. For example, the first discovered eurypterid fossil (the state fossil of New York) and the largest complete eurypterid fossil are both at the Paleontological Research Institution's Museum of the Earth. He ventured deep into the Hoh Rainforest in the Pacific Northwest, kicked off his shoes (literally!) and made his home in the trees, hidden in the moss.
Every day in Mick’s life is a different adventure; some days are spent hanging in the trees, others are spent bedding down with elk, building a mountain-man raft or running barefoot for miles. And when he does venture out from the woods into the modern world, it is to spread his message of being one with nature, before he quickly disappears back into the natural world. Having trained extensively with Mick myself I know that is real mission is that nature takes center stage.
Does Nat Geo really think that loggers spend time cutting nice little slices off of logs so mountain men can stop on by and make flintstone carts out in the middle of nowhere?.
How do they avoid the usual consequences of inbreeding—i.e., the mom fish using the sperm of her male offspring? He will gradually melt into her until there’s nothing left but sperm, which she will be able to use as needed to fertilize her eggs. We consulted with Somaweera, who thinks Aaejeewa may have seen a reptilian rainbow known as the hump-nosed lizard, Lyriocephalus scutatus.
Actually the animal had been seen before by locals and indigenous hunters who helped researchers identify it. If it was a perpetual pleasure down to the last cell, it wouldn’t be so bad for the poor male fish.
Afterwards, they dwindled in diversity but not necessarily abundance during the rest of Paleozoic.
Definitive bryozoan fossils appear in the Ordovician, although some recent discoveries may push their first appearance in the fossil record back to the upper Cambrian.

The colonies can encrust (hence their name) hard surfaces or form expansive frond-like structures.
They are found across North America but are particularly common in New England and the Ohio River valley .
There are at least 62,000 extant species, and perhaps as many as 150,000 gastropod species alive today. Some were detritus feeders, others were active predators able to drill holes in the shells of other gastropods to reach the animal within!
Index fossils are used to determine the age of sedimentary rocks and correlate them across a continent or around the world. For example, the Indiana Limestone is a popular building stone (see it on the National Mall and the Empire State Building) nationwide that is chock full of fossils. He was only rarely seen by the outside world, until he agreed to let our film crew record his unusual life.
A supposed guy that has been barefoot for 25 years in the bush and yet his toes are together like only wearing shoes will do to feet. Reason I ask is because I have been dirtier than he has ever been in the two episodes I unfortunately watched in 8 hours of working in my yard on a summer’s weekend doing landscaping. Don’t you all realize we live in a world of phony made up reality tv shows and the only concern is the bottom line. His whole goal is to preserve the 101 forest for future extreme survivalist such as you and your “offspring”! Often animals may be known to many but not yet scientifically recorded by scientists as a separate species.
Moments later, a prey bird (hawk?) swooped down, picked up the bird in its talons, and flew off.
The last few trilobite lineages were extinct by the end of the Paleozoic Era, 251 million years ago. Bryozoans (also called "ectoprocts") are still extant, with about 5000 living species today. Upright frond-like colonies, such as those on the National Fossil Day artwork, were common during the Paleozoic. Individual rugose coral polyps were stationary and constructed calcium carbonate (limestone) frameworks. Following the development and diversification of hard parts in the early Cambrian, invertebrate animals were much more likely to be preserved as fossils.
Massive reefs and other limestone deposits constructed or inhabited by marine invertebrates are important source rocks for petroleum as well as sources of immense quantities of building stones.
From searching for food to diving into rivers and scattering his father’s ashes from a mountaintop, come along for an epic journey and meet The Legend of Mick Dodge. Watch him as he catches those crabs and the way he hold them coupled with the shakey camera work. Mick Dodge could be a CEO of a Fortune 500 company but if the ratings are there its staying on the air. It had a wonderful titanium blue colour body and its legs and tail were dark blackish blue. They range in age from the Ordovician to the Permian but are most diverse in rocks of the Silurian and Devonian (see a time scale).
At the end of the segmented body is a telson that can be a spike, a paddle, or set of pincers. All told, trilobites scuttled along the floors of Earth's oceans for around 290 million years. Other important groups include brachiopods, bivalves, ammonites (Mesozoic ammonites were included on 2011 National Fossil Day artwork), graptolites, and echinoderms.
Therefore, much of our modern society is fueled by, or built upon, fossil remains of Paleozoic marine invertebrates! A variety of Paleozoic invertebrates can be discovered at Mineral Wells Fossil Park (Texas).
He picked blackberries barefoot with pith getting punctured by the vine needles on the ground. They are obviously dead or mostly dead and he is shaking them to make it look as if they are moving. Use you survival skills to locate the remote from you cushy couch and and let your thumb do you walking!!
Although the telson looks similar to a scorpion's stinger, it is unlikely that eurypertids could sting.
By comparison, dinosaurs lived for about half that amount of time and the human genus Homo has been around for not quite one percent of that span.
We also contribute to the society that has kept “your home,”, mostly free and clear of all people with no contribution from you personally in many many years!
Nevertheless, you probably wouldn't want to tangle with one that was longer than you are tall! The blue collar workforce keeps it going for ya, so loggers show up, so there are roads, you still come to the city!
Eurypterids probably ate, or scavenged, just about anything they could catch or fit in their mouth. A long white beard drapes his face and tattoos of roots adorn his feet, marking the connection he feels to the path he walks.
And I don’t care how tough his feet are, the constant wet would make him a tenderfoot in no time.
