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

Hello, friends. This specimen comes from the Catskills, New York and is from the Helderberg Group, Lochkovian or Lowermost Early Devonian in age. It could be from Becraft Mountain. It's not a rhynchonellid, it's too flat and there's no notable fold or sulcus. It develops second second order costellae half way toward the anterior margin : I have a couple of not very convincing thoughts but would be very interested in your opinions. Thank You.

Looking to identify this Early-Devonian (Helderberg) Coral
FossilRPalace posted a topic in Fossil ID
Hello everyone, I've been working on extracting this piece of coral from the Rock Cut Quarry, located in Syracuse, New York. The part of the quarry wall this piece came out of is part of the Helderberg Group, sitting below the Onondaga Formation. I was looking forward to see if anyone had some input on identifying the species of coral. I believe its Favosites sphaericus. Cross-section: Top close-ups: -

I know this trip happened a while ago, but I’ve been pretty busy as of late finishing up the school year and such and haven’t had a chance to make a trip report. Hopefully y’all find this interesting.

Gastropods: Diaphorostoma depressum Platyceras spirale? Tremanotus profundus (very flattened specimen).

I found this fossil last weekend at the road cut along Rickard Hill Road in Schoharie, New York. It is from the Lower Devonian Kalkberg formation. The surface has no texture at all. The fossil has a thickness of about 1mm. Originally I thought it was less than 2 inches long and wide but I was able to prep out the rest of the fossil due to the softness of the matrix. It is about 3 inches wide and long.

Sunday was the warmest and most pleasant day so far this spring. I decided on a solo venture up north to Schoharie County, N.Y. My destination was two road cut sites which expose the Lower Devonian Kalkberg Formation, part of the Helderberg group. The primary attractions here are the abundance and diversity of fossils, and very good preservation. The first road cut site is immense and I spent about three hours surface collecting. Most of my finds were brachiopods, some very nice specimens of Leptanena rhomboidalis, Discomyorthis oblata, Meristella, sp., Costistroponella sp., and a variety of R
