D.R. Johnson Posted September 19, 2018 Share Posted September 19, 2018 Can anyone tell me what this is? I was thinking it was some sort of coral. I found it on the Jurassic Coast of England. Link to comment Share on other sites More sharing options...

So that's not a coral at all but an invertebrate animal? Something similar to a crinoid? Link to comment Share on other sites More sharing options...

Yes, but closer to coral than crinoid. Coral is also an invertebrate animal. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Well, you just have to look reeeeeally close to spot the coral spines. Link to comment Share on other sites More sharing options...

BobWill Posted September 20, 2018 Share Posted September 20, 2018 I've seen bryozoans that look a bit like that but it also reminds me of the impression left by a Trigonia. Link to comment Share on other sites More sharing options...

Are/were Trigonia existant in the Jurassic? I supppse there are smaller Trigonia than we find here in North Texas. I agree it does resemble an impression of a bivalve or brachiopod. Would you be able to get a closer in shot of the detailed part of the specimen? Also, on the bottom center of the pic is this. It is fuzzy, but it appears to be another fossil shape. May we have a clearer shot of it? Other unique features in the rock may also aid in confirming what it is. May we see the whole of it and from other sides or angles?

That's what I would call a successful run. I don't know about sizes of different species. Link to comment Share on other sites More sharing options...
HansTheLoser Posted September 23, 2018 Share Posted September 23, 2018 My vote is also for an imprint of Trigonia. Not a coral. Trigonia itself is extinct, but another genus of the family (Neotrigonia) reached the extant. Link to comment Share on other sites More sharing options...
abyssunder Posted September 23, 2018 Share Posted September 23, 2018 The matrix looks close to the holding matrix of the Osmington Mills Trigonia beds, so I guess it could be a bivalve imprint similar to Myophorella (maybe M. clavellata?).
