The Devonian period is known as "The Age of Fish", but could also be known as "The Age of Brachiopods." In the Early / Lower Devonian, brachiopods reached the height of their diversity towards its end in the Emsian. We see the ancestral groups occurring, lingulids, craniids, orthids, protorthids, pentamerids, rhynchonellids and strophomenids, as well as the later successful groups we have seen before such as atrypids, athyrids and orthotetids, plus the rise of spiriferids, spiriferinids and productids and the beginning of the terebratulids. By the end of the Devonian , several of these g

Here is a reconstruction of the orthocerid Striacoceras typum, eating one of the last surviving Eldredgeops rana trilobites. Two Botryocrinus crinoids wave in the current, and a colony of Pleurodictyum feeds on planctonic organisms.

How rare are phragmocones from cephlapods? Are they something you need to get into a quarry to find, or can you recover them out of roadcuts? This is for the Midwest, like Illinois, Wisconsin etc.

Hi everyone! I just got back from a trip to Penn Dixie Fossil Park near Buffalo, New York, and found some pyritized cephalopod fossils. Penn Dixie has rocks form the Givetian of the Devonian from the Hamilton Group. A young ammonoid is easily identified as Tornoceras uniangulare, but the other orthoconic fossils are harder to ID. I am pretty sure the small but more complete one is a Bactrites, because the siphuncle appears to be almost ventral, the distance between the septa, and the slightly slanted suture (after looking at Ludwigia's). The preserved shell is very smooth and couldn't be from

Ammonite and orthocerid fossil
Jhester posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello! First time posting here, my in-laws run an estate auction business in Idaho and they recently came upon this fossil. We're trying to figure out if it's real or fake. We were told it's from Morocco. It's about 70cm by 50 cm, somewhere around 25kg. Let me know if there's a better image to take. Any help is much appreciated! Jeff
