Asa Kaplan replied to the topic Any ideas as to what these are? in the forum What Is It? 4 years, 8 months ago
4 years, 8 months ago4 years, 8 months agoI don’t know about the big trapezoid, but the little lineated piece certainly looks like vascular plant material. Land plant even. I find these in Middle Devonian shaley limestones, even those whose paleoenvironments had paleodepths below normal wave-base.

Among orthotetidines, this publication lists only Schellwienella? cf . S. alternata Weller, 1914, with some good photos on plate 1.

5 years, 3 months ago5 years, 3 months agoDavid, nice fossil. If this is definitely from the Madison Limestone then it is Mississippian in age — far too young to host Rafinesquina or Strophomena. I do concur that it is a strophomenide brachiopod, most likely an orthotetidine. This article is a good jumping-off point:

Asa Kaplan replied to the topic Identify this! in the forum What Is It? 5 years, 10 months ago
5 years, 10 months ago5 years, 10 months agoI’m with Jack — this looks like a Phacopid trilobite, perhaps even Phacops. In WV these are found in Middle Devonian rocks like the Marcellus Shale and the Mahantango Formation. Mahantango and Marcellus trilobites lived about 385 million years ago.
But the Eastern panhandle of WV….aren’t all those shales metamorphosed? Maybe not all, but all…[Read more]

5 years, 10 months ago5 years, 10 months agoOh, I see. Thanks, Lisa. I would like to see better support on this website for event subscription, so that updates go out to those folks who intended to attend. Otherwise, let’s leave event functionality to a platform like Eventbrite or even Facebook that can handle the relevant tasks.
Thanksgiving food………..mushroom gravy. I would like to…[Read more]

Asa Kaplan replied to the topic I found this in the forum What Is It? 5 years, 11 months ago
5 years, 11 months ago5 years, 11 months agoThe rock there is either early Cenozoic or else Mesozoic. Ediacarans are out of the question, not only for this reason, but for morphological reasons: no known Ediacaran is spiral- or tube-shaped.
This appears to be the trace of a worm or other creature that fed in a spiral outward from a central starting point. It consumed the sediment whole and…[Read more]

6 years ago6 years agoThanks for the tag, EG! I have no idea what this webinar is or where to find it, but I’d like to learn about the lesser-known soft-bodied preservation localities like Blue Island. And maybe a review of some amazing sites that are now off-limits (rather than played out).

Asa Kaplan replied to the topic Help identifying fossil from Texas in the forum What Is It? 6 years ago
6 years ago6 years agoAlthough often mistaken for a trilobite, this is not a fossil at all. You will note that you can crush it with your fingernail.
It is the egg case of a praying mantis from the 2010’s.

6 years, 2 months ago6 years, 2 months agoJulie @julie-niederkorn, you have opened my eyes! I was assuming the entire fossil to be a pygidium, but now I take your point that it comprises the whole thorax plus the pygidium. And that makes it an excellent match for the thoracopygidium of Thaleops o…[Read more]
