Winner of the December 2021 Invertebrate/Plant Fossil Of The Month
digit posted a topic in Fossil of the Month
The winner of the December 2021 IPFOTM goes to... Dipleura dekayi trilobite - Devonian, Moscow Fm - New York Congratulations to @KompsFossilsNMinerals !!! -
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.- 1 reply

An article on the Cretaceous-Eocene Trans-Saharan Seaway in "Natural History" magazine
siteseer posted a topic in Fossil Literature
In the September 2021 issue of "Natural History" magazine, there's an article, "The Trans-Saharan Seaway," by Devin Reese, Robert V. Hill. and Leif Tapanila. Anyone who collects fossil shark teeth knows Morocco and other parts of northern Africa were submerged by an inland sea as recently as the early-middle Eocene but there was also an arm of the sea that cut south all the way from what is now Algeria to what is now the Gulf of Guinea. The article summarizes the work of a team of geologists and paleontologists across a ten-year period in the early 2000's. It reviews a number of fossil find -

COMPLETED, THANKS!: Request for a missing plate from a classic trilobite paper
pefty posted a topic in Documents
Hi, I'm looking for help locating a plate that seems to be inexplicably missing from the online version of a classic trilobite paper. The plate I'm seeking is PLATE XXVI (26) from Lehi Hintze's 1952 paper Lower Ordovician trilobites from western Utah and eastern Nevada. Utah Geological and Mineralogical Survey Bulletin 48: 249 p. The only online version I've found, which seems to be missing plate XXVI, is here: https://ugspub.nr.utah.gov/publications/bulletins/b-48.pdf If anyone has access to a paper copy and can post a scan of PLATE XXVI (26) here -

The last weekend of September, I decided to visit some of my central Texas sites. I had been looking for a tetragamma for some time - the first one I found was collected illegally, totally by mistake, on federal property. And it was far from a perfect specimen. Well, after a few years of being teased by broken tetragamma bits, I found this beauty. I believe this is a tetragamma streeuwitizi - collected from comanche peak limestone. Please forgive the situ pic, motion picture was activated, and the sun was too bright to tell that it was a poor quality image until later.

Again, here is another invertebrate I have not been able to identify. Either way, my original guess was a trilobite pygidium, until I reviewed the fossil under different lighting, and then saw that it matched no known trilobites from this formation. So I am at a loss here. It is Pridoli, Silurian. For anyone who is interested, this came from a recent excursion to the Leighton Formation. It was found in a layer that contained only Chonetes bastini brachiopods and a few ostracods - with some possible fish bits. In the pictures below, the fossil is shown und

Looking for help with this Early Ordovician (Floian) trilobite from the Powell Dolostone of Arkansas, USA. The specimens (GRAY FIGURE below) were identified by Taylor (1968) as cf. Lannacus nericiensis Wiman, but that species (now a species of Megalaspides) doesn't seem like a great match, as the author notes in the paper. In fact, I'm not sure that proper Megalaspides even lived in North America. Last week, an Arkansan found another asaphide specimen (MAIZE AND BLUE FIGURE below) in these same rocks, which may or may not be the same species as the specimens described by Taylor.

Triassic Bivalve Imprint from the Triassic Basin NC (~230 Ma)
AlexSciChannel posted a topic in Member Collections
Here is a picture of a Bivalve imprint I found whilst in a Creek in Western Wake County. I was in the Triassic Basin and they have fossils dating back around 230 Ma ± 2 ma. It was part of the Carnian Stage of the Triassic part of the bigger Newark Supergroup. I presume it is a freshwater genus but I don't hear much about freshwater Bivalves when it comes to Triassic fossils. -
