Goniodonts - strange echinozoan teeth from the Carboniferous
TqB posted a topic in Member Collections
I was surprised to see this specimen for auction and pleased to win it. It's Anguloserra thomasi, a rare tooth from an ophiocistioid echinoderm and comes from the same locality as the holotype described here (abstract only): Haude & Langenstrassen 1976. I've been interested in these since finding three similar specimens in the UK that took a while to identify - shown in the next post. It's preserved as an impression - most material in this matrix is decalcified. Carboniferous, upper Mississippian, Culm beds (equivalent of Brigantian and Arnsbergian beds in UK), Aprath, Germany. Scale in mm. Here's the holotype from the linked paper (a latex cast):- 21 replies

Eurypterid or sponge bored orthocone? Revisiting a Mississippian puzzle
TqB posted a topic in Fossil ID
A while ago, I was convinced that this was an orthocone with possible sponge borings though it was never really resolved. http://www.thefossilforum.com/index.php?/topic/77979-strange-infestation-on-orthocone-shell-mississipian-ne-england/& @Al Dente suggested eurypterid as a possibility which I argued against, largely because they've never been found around here. However, a friend of mine has now found some undoubted eurypterid fragments in equivalent beds in Scotland, 120 miles away or so and where the faunas have much in common. He's pretty sure that this is indeed eurypterid (based on just a couple of closeup photos). I'm rather hoping it is though the boring sponge is also pretty interesting. Searching throws up Adelophthalmus as a distinct possibility, based on the ornament (see reference and drawing at the bottom of the post). So here it is again - eurypterid or bored orthocone? Brigantian (Mississippian) marine shale, Co. Durham, NE England. (Many more photos on the original thread, including very close up. The little rings are preserved in solid pyrite and go right through the shell/carapace.) From this paper on Pennsylvanian Adelophthalmus https://www.foss-rec.net/8/3/2005/fr-8-3-2005.pdf- 11 replies
