I had this one for a while now ,then saw the current paywall and decided to post this. Great insight into Mid Paleozoic vertebrate locomotion,musings on forelimb morphology and its role in terrestrialization,great grayscale 3d reconstruction . Short,and to the point. Ichtstega!NAE2012.pdf

How did some early Paleozoic animals expand to distant continents so fast?
Hapchazzard posted a topic in Questions & Answers
I've noticed that a lot of clades that first appear in the early Paleozoic seem to immediately be present across the globe, even though the continents at the time were mostly disconnected and separated by oceans. For example, (calcified) trilobites suddenly appear in Cambrian Stage 3, but are already present in Laurentia, Siberia and parts of Gondwana, despite the vast distance and oceanic separation of the landmasses. Similarly, Rugose corals appear in the late Middle Ordovician, but already seem to present across the equatorial regions of the globe. How did these benthic/sessile -

Hi, I was just wondering what was considered large for a single Edestus heinrichi tooth. I have recently bought one and it was around 1.6" wide. It was labeled as being big, but I just wanted another more experienced opinion on it. Thanks for your time.

My kids found some fossils near Roanoke, VA - It looks like they are brachiopods and trace fossils from outcrops ranging from the Ordovician to the Mississippian. Can these be more specifically identified besides generic "brachiopods"? Thanks!

On the winter solstice, we took the family out for a 7-mile winter hike. Luckily it was winter in name only, as the temps got up to almost 50 degrees. We found a nice trail near Roanoke, Virginia, that took us into the Appalachians. As the kids are still excited about our giant fossil hunting trip out west this summer, I decided to pick a location where I knew there were fossils to be found. All I know is that these were Paleozoic formations, where 450mya it was swampy mud flats. So I could tell them we wouldn't be finding dinosaurs, but we might find some shells. So they en

should be easy for US hunters,from the Devonian or Silurian of Northern France,ID?

Possibly it's just me, or does it seem there are far less posts about fossils in the west. Has this site morphed into a Paleozoic forum?

Did a quick perusal of the forum and came to the conclusion that this paper might be new to all of you. If not,I apologize beforehand to the previous poster BTW,the source publications has a reputation to uphold.Read it,by all means Cargaineslage.pdf

I posted this because East Kirkton lit. is rare. It is relatively short,and is a careful analysis of the "Faziesverhaltnisse" ,diagenesis and taphonomy of this famous site. Biotic content: amphibia/"tetrapods"/plant taphonomic mode: silicification Significance:"silicification" and "vertebrate" aren't found in the same sentence often Rolfeetal1990.pdf

Found this in my yard, which is covered in gravel, at least as much as I can afford. I hate mowing. The material is probably Paleozoic, but could be up through the Pleistocene. It is flat on both sides. Initially thought coral, but doesn't look right. Brent Ashcraft

Around 1967 Jefferies launched his preliminary ideas on "calcichordates". Many echinoderm specialists are not convinced by his ideas. But: his interpretation of functional morphology makes sense,and his plate nomenclature has been taken onboard by at least some non-adherents of his theory. Although NOT commonly found,in some parts they can be a significant part of the paleofauna. Time to meet a fascinating group of animals!
