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

From the album: Brachiopods of Platteville/Decorah Twin Cities Minnesota
Zygospira sp. Apparently there are a mystery with this genus when it comes to Twin Cities. I first noticed it only from Middle Platteville Formation - 100% nonexistent from upper Platteville Formation. Much more finer costae compare to Rostricellula minnesotensis and generally smaller. Belongs in Spiriferid family despite it strong resemble to Rhyconellid family. Then after a very long absent either the same species or a very similar species popped up again in upper Decorah formation and became very abundant. I suspects the reason for this seemly weird pattern is they may be much more speciali -
I was cleaning up my drawer with spiriferids from the Ardennes and I found a weathered one that I picked up for a particular reason. The suport of the lophophore of the spiriferid is partially visible. this lophophore is the feeding apparatus of the brachiopods and looks like a ring with tentacles. On spiriferids the lophophore suport is a typical spiral on both sides of the shell. The “spiral” is also the reason for the name of the fossil “Spirifer “= “Spiral-bearers” I'd love to se some more brachiopods in tff-members collections with preserved loph

Paulding Fossil Community Garden - LaFarge Quarry (Cecil, OH)
Fossil-Hound posted a topic in Fossil Hunting Trips
Well I'm on my way to Utah for a new career opportunity and looked up the LaFarge quarry in Paulding Co. last night. This quarry is supplied with dump trucks worth of shale from the LaFarge quarry that pulls directly from the Silica Shale formation Devonian era. The location is in the middle of nowhere and my wife gave me one hour to look around. Soon I had my five month old daughter, Clara, strapped to my chest in a baby carrier and I was quickly scrounging around looking for fossils. I can tell you that I was not disappointed though I did not locate a complete Eldredgeops roller I did walk a- 16 replies

Hey everyone, Nearly forgot to post this little beautiful dude in the Fossil ID section. I got this as a gift from the Geo-Oss fair some time ago. The only info I have on this little spiriferid brachiopod is that it’s from Canada. Now, this is probably a long shot, but I was wondering if anyone maybe recognized which location, formation and age correspond to this little dude? If the species is also recognizable that’s awesome. There were a LOT of the spiriferids in that box, all seemingly of the same species, so it’s a location at which these brachiopods a

Hello everyone, I have dwindling amounts of material from my trip to paupack to be identified. This is some spiriferids from the trilobite ridge, these were especially numerous. Some layers were basically made out of them. I'd like to get a species or at least a genus on these guys, the loose one I'm thinking of labeling and placing in a river mount, then sending it to the land owner. The formation is questionable as there are many present, although it's probably lower Devonian (although some late Silurian exist).
