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

Hoooooooooooorrrrrrrrrrrraaaaaaayyyyyyyyyyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Here we are at last, into Adam's Silurian. Thanks for looking. First up is the Lower Silurian or Llandovery and I begin with a problem. I posted this one incorrectly in Adam's Ordovician as it had got it's label muddled up with an Ordovician Favosites I had that has vanished in the move here, but is being replaced by kind forum member @Herb Anyway, this, I remember now I've found the correct label, is from the greenish Browgill Formation, part of the Stockdale Group from a cutting near Skelg

Fossil hunting trip to Hotton (Devonian of Belgium)
ziggycardon posted a topic in Fossil Hunting Trips
Hi everyone! Last saturday we went on a fossil hunting trip with the BVP to Hotton in the Belgian Ardennes. https://www.paleontica.org/locations/fossil/667 There were 2 different locations planned for the day, the first was the "Carrière de Marenne" quarry in Hotton were we spent most of the day. It was my first time at this location, so I didn't have very high expectations but we were very pleasantly surprised by the quality and quantity of the finds which made for a very productive and succesfull trip! Unfortunately like so often I forgot to make pictures inside th -
I bought a couple brachiopods not to long ago and the information that came with them says they are "Atrypha sp." but when I look up "Atrypha sp." all that I find is "Atrypa sp." I would really like to know if the information that came with them is correct or not. Thanks in advance!

From the album: Lime Creek Devonian Rockford Iowa
Atrypa devoniana. Can be confused with two other genus species even thought it is low in diversity of shapes. Its shell is fragile, and more likely to be misshaped during the fossilization progress. Juvenile can be easily confused with Spinatrypa rockfordensis. -
Yesterday we went on a fieldtrip organised by my geology club in the area of Marche en Famenne. In the morning the first stop was the visit of the "Grottes de Hotton" but me and my girlfiend didn't do this visit, so we got around 11am at the grottes to wait for the rest of the group. the weather was sunny and the temperatures very pleasant, this was going to be a very nice spring day. When the group was complete we hit the road to the quarry a couple of kilometers further. first we got a quick lesson about the geology of the quarry and safety mesures ( the sediments in t
