Terry Dactyll Posted November 29, 2012 Share Posted November 29, 2012 I dropped on this Plagiostoma lower Jurassic shell earlier today whilst out and about on the beach and although I dont collect these I just had to bring it home for a prep based on its sheer size... its a little water worn here and there but it should make a wonderful doorstop.... I'll post a photo when I prepped it... (if it looks anygood ) Has anyone else got any very large shells to share?.... Cheers Steve... And Welcome if your a New Member...

astron Posted November 30, 2012 Share Posted November 30, 2012 (edited) Very interesting topic, as I was expecting... Steve, Mike, Missourian, Gery, Christian, taj, Impressive contributions everyone!!!!!!!! This in my avatar and already previously presented shell was my favorite fossil for many years and it still remains of my favorite ones... It's about a Gigantopecten latissimus measuting 23x18x6 cm and I vividly remember my big surprise for that huge size when I found it many years ago... I have searched it and I have never found shells of this species bigger than 19 cm. I'd be greatful, if Mike or Gery or anyone else have relative to the size more info to provide...

Missourian Posted November 30, 2012 Share Posted November 30, 2012 Surely someone has pics of some of the ridiculously large inoceramids from the Cretaceous?

Terry Dactyll Posted December 1, 2012 Author Share Posted December 1, 2012 (edited) Wow.... Those pectens are huge Mike & Astrinos... I never realised they got so big....Great contributions everyone... Gery... What a stunning specimen... The very fine details are preserved I dont think I have ever come across one so good... The best one I found we have in the office... It had just eroded out and hadnt been bashed about by the waves to much so retained a little more detail than usual...

Kosmoceras Posted December 1, 2012 Share Posted December 1, 2012 Tiny compared to some of the monsters on this thread, but this one is extremely large for the location (Walton on the Naze, UK). Thanks for posting these, they have been a wonder to gaze at. Link to comment Share on other sites More sharing options...
