Tidgy's Dad Posted December 2, 2017 Share Posted December 2, 2017 Now, i found this when i was seven or eight years old, on the cut down to the beach at Kilve in Somerset, South West England. It was buried in a band of blue/ grey clay in the Psiloceras planorbis zone of the Blue Lias , Lower Jurassic. Although i'd found many lovely fossils before this was my first exceptional, "WOW!" find. I still don't know what it is and that was 45 years ago. A colonial coral colony yes, but i don't think it can be Liassic? A derived fossil from the Devonian or Carboniferous seems likely, but which one? And it shows very little signs of having been transported huge distances, as it's quite a way to the nearest relevant outcrops of those ages. Here it is : 1 Life's Good! Tortoise Friend.

abyssunder Posted December 2, 2017 Share Posted December 2, 2017 That' a pretty nice coral. I'm not a coral specialist, but here is an excerpt from P. Martin Duncan - A Monograph of the British Fossil Corals, second series. Supplement to the Monograph of the British Fossil Corals' by MM. Milne-Edwards and Jules Haime. 5 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

TqB Posted December 2, 2017 Share Posted December 2, 2017 It's definitely a very nice Liassic one - Abyssunder has it though I believe it's called Heterastraea now. I have a couple of specimens of (probably) H. excavata from the Hettangian/lower Sinemurian of Yorkshire where it's hen's teeth. 4 Tarquin Link to comment Share on other sites More sharing options...

Thank you, I had it tentatively listed as Heterastraea tomesi, but can't remember how i came to that conclusion. Hen's teeth is correct, nothing like it from that location, as far as I know, so i was beginning to doubt myself and assume it was somehow a Devonian or Carboniferous 'import'. I am most happy. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
TqB Posted December 2, 2017 Share Posted December 2, 2017 It's a great specimen - this paper describes the famous and fascinating occurrence of them growing on contemporaneously exposed Carboniferous limestone near Ogmore, Glamorgan, that's also referenced in Abyssunder's monograph (Sutton Stone). It's not very far from yours but I think they're pretty rare on the Somerset coast, different environment. https://www.palass.org//publications/palaeontology-journal/archive/38/3/article_pp529-541 4 Tarquin Link to comment Share on other sites More sharing options...

Bobby Rico Posted December 3, 2017 Share Posted December 3, 2017 Wow great specimen. I would be over the moon if I had found this coral now, let alone when I was 8. Nice fossil coral. cheers Bobby 1 Link to comment Share on other sites More sharing options...
