Haravex Posted January 31, 2018 Share Posted January 31, 2018 Ok before I go any further I appreciate all the help from the forum and will always research and look up information before asking some I feel I have an idea on but need a second set of eyes and mind. First one I thought was rebbachisauride but maybe not or it is a pathology. This one I believe to be a pre maxila ablesauride and then there are two complete limb bones the first one I suspect might be carpal however not sure and maybe turtle? and the second limb bone maybe a tibula?

Tidgy's Dad Posted January 31, 2018 Share Posted January 31, 2018 A nice lot of pieces. I would agree the first is a rebbachisaurid, and the turtle one looks turtle to me, for the others someone more knowledgeable than I will have to have a say. Life's Good! Tortoise Friend.

Haravex Posted January 31, 2018 Author Share Posted January 31, 2018 Thanks tigg I too thought rebbach but the curved tip threw me off as they are normally straight or at least what I have seen any idea on the position of the turtle in terms of anatomy wise? Again all these pieces have no id to them when bought just that they are from kem kem beds. Link to comment Share on other sites More sharing options...
Troodon Posted January 31, 2018 Share Posted January 31, 2018 Believe this is a Premaxillary tooth of an Abelsaurid Your first tooth is that of an indeterminate sauropod. Identification of these type teeth is very problematic and cannot be assigned to a genus. Reminder we do not have any skull material from any sauropod in the Kem Kem. Best described as a Neosauropoda disregard what everyone is selling. . The other bones are reptlian most likely turtle Link to comment Share on other sites More sharing options...
LordTrilobite Posted January 31, 2018 Share Posted January 31, 2018 Yup I agree, indeterminate Sauropod tooth. And I agree that the other tooth could be an Abelisaurid premaxilla tooth. Here's one of mine for reference. Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
Troodon Posted January 31, 2018 Share Posted January 31, 2018 As far as the shape of the tooth here are some examples and you can the shape differences of unerupted and functional teeth. https://www.researchgate.net/publication/250926259_Evolution_of_High_Tooth_Replacement_Rates_in_Sauropod_Dinosaurs Link to comment Share on other sites More sharing options...
Haravex Posted January 31, 2018 Author Share Posted January 31, 2018 Thank you for such fast and informative responses can't believe I missed that sauropod topic but very insightful. Any idea what type of turtle bones they are I.e. carpal, metatarsal, tibula ect? And again thank you will post later some possible skull element has a lot of sutures and good shape for skull candidate material. Link to comment Share on other sites More sharing options...
Haravex Posted February 1, 2018 Author Share Posted February 1, 2018 Ok this is the possible skull part based on the sutures but cant place it in my mind where it would fit i know @lordtrilobite has some good knowledge and expeirance with this. do note that on the second and third to last picture there is a lot of matrix that is hard and will need to be prepped at home.

Haravex Posted February 1, 2018 Author Share Posted February 1, 2018 I forgot measureents along is 20cm and at widest point is 7cm Link to comment Share on other sites More sharing options...
LordTrilobite Posted February 1, 2018 Share Posted February 1, 2018 I agree that it looks like a skull part. It's a tough one. With a long curved shape like that, maybe part of a nasal? Cleaning it up more might show better where it's broken and where there are sutures as well as the outer surface.

Haravex Posted February 1, 2018 Author Share Posted February 1, 2018 Yes I agree will have to wait until the 10th when I arrive home to clean it up however. Link to comment Share on other sites More sharing options...
Troodon Posted February 1, 2018 Share Posted February 1, 2018 The reptilian bones are probably hand or foot and that does look like a skull element. Like LT said cleaning and more pictures might get you some answers Link to comment Share on other sites More sharing options...

In your example I think you mean tibia which is the larger That tooth is really nice, I’ll be looking out for one of those!

Haravex Posted February 2, 2018 Author Share Posted February 2, 2018 Thanks troodons, and yes John was a little bit unwell when typing that message (That is my excuse and I'm sticking to it ) Anyway I think I have made the correct identification with this one but a second opinion is always welcomed Carchardonosaurus metatarsal Forgot again length is 390mm Link to comment Share on other sites More sharing options...
Haravex Posted February 2, 2018 Author Share Posted February 2, 2018 Also there is this vertabrae not sure if it is croc or theropod maybe @LordTrilobite can show some light on the identification. Link to comment Share on other sites More sharing options...
LordTrilobite Posted February 3, 2018 Share Posted February 3, 2018 It's say it's a match with this caudal vert I have. I was told at the Natural History Museum in Leiden that this was dinosaur. While @Troodon says this is croc due to the curvature on the side surfaces of the dorsal spine. So I'm not quite sure yet. I think I might lean more towards croc as Troodon has a point that it looks similar. But What I find interesting is that the zygapophyses seem to be partially hollow, which makes me think of Theropod.

Haravex Posted February 3, 2018 Author Share Posted February 3, 2018 Yes I know what you mean the same parts you mention also look hollow honeycomb like structure. Would this be a dorsal vertebrae? Link to comment Share on other sites More sharing options...

Haravex Posted February 3, 2018 Author Share Posted February 3, 2018 This is also one of many interesting hollow bones I picked up. Link to comment Share on other sites More sharing options...
Haravex Posted February 3, 2018 Author Share Posted February 3, 2018 There is also this one which fits the characteristics troodon described about the twist and the fine serations on the mesial side, and on the distal side the serations are stright not angled like ablesauride teeth, it is 14mm straight line.

Troodon Posted February 3, 2018 Share Posted February 3, 2018 I'm in the crock camp on that vert, too many wrinkles on the back edge and the spine is not flat and very perpendicular. The only cretaceous dino vert I have around this shape a dorsal its very smooth with sharp edges. The spines are also flat on the flat face no ridges. Why do you think that tarsals is from a Carch?

Troodon Posted February 3, 2018 Share Posted February 3, 2018 That tooth looks Dromaeosaurid like and might be. The bone does look like a femur with the condyle missing. Looks reptilian Link to comment Share on other sites More sharing options...
Haravex Posted February 3, 2018 Author Share Posted February 3, 2018 Do reptiles have hollow bones? Also again for the carchar it's size yes and also the fact it is completey hollow but maybe my understanding is wrong on this? Link to comment Share on other sites More sharing options...
Haravex Posted February 3, 2018 Author Share Posted February 3, 2018 Here are some additional photographs the bag of matrix is what I carefully removed from the centre of the bone and is just sand and a few pebels. Also excuse the rug making a cameo appearance Link to comment Share on other sites More sharing options...
