Hardly anybody ever talks about the Cambrian fossils of the southern midcontinent (USA). They're super-underappreciated. Show us what you've got! Here's one to start us off: Thorax and pygidium of a trilobite, possibly Orygmaspis, typically referred to as "Orygmaspis cf. Orygmaspis llanoensis" but probably a different species altogether. Note the two pairs of macropleural spines marking the final thoracic segments. Davis Formation (late Cambrian: Furongian), south side of Highway 8, St. François County, Missouri.
Could someone suggest a professor of Invertebrate paleontology, currently working, who has an expertise in New York State Devonian Era strata? I have a Phyllocarid specimen that may be of scientific value. Thank you
Though I have a feeling I'm going to be embarrassed for asking what turns out to be obvious, but: I was hoping someone would be willing to give me a hand getting access to the 2007 Suppl. to Part H (Brachiopoda), Vol. 6 of the Treatise. The archives only appear to go back to 2010. Do Paleontological Society members not have access to earlier volumes? Thanks! Wendell
The title pretty much sums it up. I've reviewed every publication I can access, still having much trouble with what first appeared to me to be an easy I.D. As you can see, the material has typical striated lines on its outer surface. On each striated line, there are "dots" from one end of the line to the other. Horizontally, the dots match up with the dots on the left and right of the striated lines beside. It would seem identifiable to me based on that type morphology, but I just can't find an example with such morphology. Please help with this tough I.D. and thank you all in advanc
