Goldkaiser Posted June 27, 2016 Share Posted June 27, 2016 Recently I brought 8 1/2 kilo of Aguja formation micro matrix excavated in Texas. The Rock is mastrictiaan in age(late Cretaceous). The start of my sieving tonight has revealed a few important fossils, these however have got me truly excited and I hope they are what I think they are. If all goes well I will finish tommorow and be able to photograph everything. Please forgive the terrible photography it is night time now and so I can't use the natural light but was excited to share. scale bar is seen in CM.

Runner64 Posted June 27, 2016 Share Posted June 27, 2016 They're all theropod teeth, maybe raptor? Really neat finds! Link to comment Share on other sites More sharing options...
Ridgehiker Posted June 27, 2016 Share Posted June 27, 2016 There's a lot of possibilities on a theropod tooth. The shape of the tooth and angle of the serrations 'suggest' the genus Saurornitholestes....however, even a tooth held in the hand can be be difficult to identify.

jpc Posted June 27, 2016 Share Posted June 27, 2016 yup... a couple of little theropods. Link to comment Share on other sites More sharing options...
Troodon Posted June 27, 2016 Share Posted June 27, 2016 (edited) The Aguja formation of West Texas is a late cretaceous deposit Campanian in age. The dinosaur assemblage found there is similiar to what is found in Alberta's Campanian deposits: Richardoestesia, Tyrannosaurids, Saurornitholetes, Dromaeosaurus etc. but I don't think a lot has been described. An excellent paper is shown below but it's not an open paper. http://www.sciencedirect.com/science/article/pii/S0031018214005835?via%3Dihub Photo of small theropod teeth from this formation 1) tyrannosaurid indet 2) cf Richardoestesia 4) cf Saurornitholetes 3, 5-8) Indeterminate theropods Edited June 28, 2016 by Troodon 1 Link to comment Share on other sites More sharing options...
Troodon Posted June 27, 2016 Share Posted June 27, 2016 image.jpeg This tooth is complete, if you could provide a sharper image straight in I can try to get you to a genus level. Link to comment Share on other sites More sharing options...

Goldkaiser Posted June 28, 2016 Author Share Posted June 28, 2016 I've also found several of these teeth this morning would I be right in assuming a form of crocodile maybe? Link to comment Share on other sites More sharing options...
Troodon Posted June 28, 2016 Share Posted June 28, 2016 Can you take an image of the other side of that tooth and position it straight on not at an obtuse angle. That new tooth looks like a Croc. 1 Link to comment Share on other sites More sharing options...

Troodon Posted June 28, 2016 Share Posted June 28, 2016 Thanks you now I can clearly see the tooth. Looks very similar to number 4 on the photo of post 6. Described as "cf. Sauronestlestes" which is a Dromaeosaurid type of theropod. 3 Link to comment Share on other sites More sharing options...
