lelani Posted June 24, 2016 Share Posted June 24, 2016 I received these dinosaur bones from an ex boyfriend about 30 years ago when I lived in Colorado. Since then its just been stored away. There is a tooth missing when I dropped it ..yikes and the other was glued on. Gosh I feel so bad for treating it like a non special item as I imagine it could be valuable. Ive been told it could be a trinasauras? I have no clue. Would anyone know? Thank you. Link to comment Share on other sites More sharing options...
Vieira Posted June 24, 2016 Share Posted June 24, 2016 Can you show better pictures? Look likes a replica to me... Wait for more comments.. Link to comment Share on other sites More sharing options...
Troodon Posted June 24, 2016 Share Posted June 24, 2016 Looks like a lower Xiphactinus fish jaw definitly not dinosaurian. Teeth look replicated but like Vieira said need better pictures. Link to comment Share on other sites More sharing options...
Fossildude19 Posted June 24, 2016 Share Posted June 24, 2016 Definitely not a Tyrannosaurus. I like Frank's idea of Xiphactinus (fish) Jaw.

zekky Posted June 24, 2016 Share Posted June 24, 2016 Not a dinosaur. Link to comment Share on other sites More sharing options...
jpc Posted June 24, 2016 Share Posted June 24, 2016 Yeah, not a trinasaurus...nor Tyrannosaurus. I think Xiphactinus is a better educated guess. Link to comment Share on other sites More sharing options...
siteseer Posted June 24, 2016 Share Posted June 24, 2016 Troodon, My first impression was actually phytosaur. The Chinle is exposed in southern Colorado at least. I'm away from my books - just thought I'd throw that out there until clearer photos were posted. Jess Looks like a lower Xiphactinus fish jaw definitly not dinosaurian.

Troodon Posted June 25, 2016 Share Posted June 25, 2016 It's possible, here is isurus's photo of a Phytosaur in the Museum in Northern Arizona. Jaw looks thinner than the one in the initial post. Will need those photos but still leaning towards Xiphactinus Link to comment Share on other sites More sharing options...
zekky Posted June 25, 2016 Share Posted June 25, 2016 A tooth close up would help Link to comment Share on other sites More sharing options...
lelani Posted June 27, 2016 Author Share Posted June 27, 2016 (edited) Thank you all for your response. Vieira (btw, very nice name) I believe that the tooth is not a replica or imitation because when I umm dropped the slate, the top layer of the jaw broke off. And the material underneath was crystalline rock like (see pic), similar to petrified wood. Also the tooth would not break off so easily if it was a replica as I imagine the material would be more solid and strong. Troojan, thank you for the Phytosaur pic. But I think the jaw of my item is wider, thicker in girth and shorter in length. And it doesn't seem like the fossils on the left of the jaw are fish like bones. I have added a pic of the slab with the broken jaw off and a higher resolution of the jaw. Hopefully you can zoom in on the details. Thank you for your help. It is Appreciated.

lelani Posted June 27, 2016 Author Share Posted June 27, 2016 From the pic I found, I think you may be right Troodon and Fossildude19.... that it could be a Xiphactinus. Link to comment Share on other sites More sharing options...
lelani Posted June 28, 2016 Author Share Posted June 28, 2016 Is there anywhere i can get an estimate of the item's value as I do want it at a place where it would be appreciated. Thank you Link to comment Share on other sites More sharing options...
CraigHyatt Posted June 28, 2016 Share Posted June 28, 2016 Is there anywhere i can get an estimate of the item's value as I do want it at a place where it would be appreciated.

Thank you I would contact Glen Rocker of PaleoSearch who specializes in marine fossils from the Kansas Chalk. He can give you an estimate and an idea of what you can do with it. http://www.paleosearch.com/contact-us/ Link to comment Share on other sites More sharing options...
Xiphactinus Posted June 28, 2016 Share Posted June 28, 2016 It's definitely a Xiphactinus jaw. As far as value...they are pretty common in the chalk of W. Kansas. The matrix looks like Niobrara Chalk of W. Kansas. Link to comment Share on other sites More sharing options...
lelani Posted June 29, 2016 Author Share Posted June 29, 2016 Thank you Troodon for your suggestion as I do not just want to donate something that was given to enhance my life in whatever manner I deemed it to be. Like would anyone just give away a classic Thunderbird automobile just cause the owner could not drive? However I thank you all for your help in identifying my item.
