JohnBrewer Posted May 9, 2016 Share Posted May 9, 2016 Hi folks I've been digging through a few lumps of rock I collected a couple of years ago from Aust, Gloucestershire, UK which is rich in plesiosaur stuff among other things. I found these two pieces (three now :/ ) which were touching. I'm guessing they're plesi paddle bones. Am I right?

Fossildude19 Posted May 11, 2016 Share Posted May 11, 2016 Very neat finds, John! Well done. Not familiar with plesiosaur material, so, unfortunately, I can't help there. Maybe someone more local will weigh in. Thanks for posting the mystery here, though.

jpc Posted May 11, 2016 Share Posted May 11, 2016 I can't say much about the first one, but you may be right on the second bone. Plesiosaur finger bones tend to be hourglass shaped, but all the ones I have seen are longer than this. Link to comment Share on other sites More sharing options...
Ludwigia Posted May 11, 2016 Share Posted May 11, 2016 I'd say that's what they probably are. At least 2 & 3. Can't quite figure out the first one though. I also agree with JP. They are longer generally, but maybe that's from a juvenile. It's not a vertebra at any rate. Greetings from the Lake of Constance.

Mike from North Queensland Posted May 11, 2016 Share Posted May 11, 2016 Comparing your specimens to the Australian material I have seen, the first photo definately has that plesiosaur paddle look to it. With the size it would have to be a new born so that could explain the stubby phalanges but species is more likely. Mike D'Arcy Link to comment Share on other sites More sharing options...
Auspex Posted May 11, 2016 Share Posted May 11, 2016 I wonder whether the "puck" mightn't be a metapoidal or mesopoidal?

Welsh Wizard Posted May 12, 2016 Share Posted May 12, 2016 Hi John have you got an end on pic of the first photo. It may be an late triassic ichthyosaur humerus or femur rather than a plesiosaur paddle. I'm not sure about the other two. They sorta look plesiosaur but they don't as well. Do either of them have little holes in them? Regards Nick Link to comment Share on other sites More sharing options...
DE&i Posted May 14, 2016 Share Posted May 14, 2016 Hi John, Photo's 2 and 3 look distinctly more like Plesiosaur vertebrae. As I'm sure I can see the remnants of a neural arch facet.

Do either of them have little holes in them? Regards Nick Hi NickI've now managed to take some images With the other circular bone, there are no holes I can see and it is in fair condition unlike the paddle shaped bone. The circular bone doesn't look like any of the plesi verts I have, not that I've got a stack and I've not got any from the tip of the tail if that's where it might come from. Darren, what part do you think shows evidence of a neural arch? I'm not 100% sure of what you mean. I could take more images if that would help. Hoping it's a juvenile, that would be cool.

DE&i Posted May 19, 2016 Share Posted May 19, 2016 Hi John, Photo 2 is very similar to the Plesiosaur vertebrae in this picture ( 1 ).Although the facets on yours are quite water worn. Here's a picture ( 2 ) of a juvenile neural arch with spine.This sits on top of the curved shape facets. Hope this helps.

JohnBrewer Posted May 21, 2016 Author Share Posted May 21, 2016 Thanks Daren, I understand now. Are those plesi bits from your collection? They look fabulous. John Map of UK fossil sites Link to comment Share on other sites More sharing options...
DE&i Posted May 21, 2016 Share Posted May 21, 2016 Hi John, No problem at all. Luckily when you took the photo I think you subconsciously picked out the tell tale feature to identify the bone. There not my Plesiosaur bones I'm afraid but I have many with the same characteristics such as this one below.

Mike from North Queensland Posted May 21, 2016 Share Posted May 21, 2016 John The more I look at the initial post the more I think your larger piece from your initial post is part of a vertebrae. I also agree with the others the other piece from the initial post looks like a small vertebrae Mike D'Arcy Link to comment Share on other sites More sharing options...
Welsh Wizard Posted May 22, 2016 Share Posted May 22, 2016 Hi John Thanks for the additional photos but it is hard to tell with bone pieces from Aust. Defo two verts, but the other piece I'm still not sure Nick Link to comment Share on other sites More sharing options...
JohnBrewer Posted May 22, 2016 Author Share Posted May 22, 2016 Thanks again everyone. I think I should have be clearer with my photos and description tho: This is one piece broken unfortunately. The part sticking out on the top right is another separate piece of bone. These are the two parts which were joined together in the first place, it's the same bone as in the first image. It was the tear drop shap that made me think it might be a paddle bone. Do you guys think the vert is from a juvenile or could it be the very tip of an adult tail or is it to difficult to ascertain? I love Aust bone bed, I pick up the chunky bits other have left behind, amazing what can be found sometimes:) John Map of UK fossil sites Link to comment Share on other sites More sharing options...
JohnBrewer Posted May 22, 2016 Author Share Posted May 22, 2016 The two bottom images are not to scale. If you turn around the bottom image 180 degrees it joins the top of the image in the middle John Map of UK fossil sites Link to comment Share on other sites More sharing options...
