Raptor9468 Posted May 17, 2020 Share Posted May 17, 2020 I just got this bone fragment refered to as a scute from either an ankylosaur or a turtle from the lance formation. Upon further inspection,I dont see the typical ankylosaur blood vessels or the turtle carapace type features. Link to comment Share on other sites More sharing options...

GeschWhat Posted May 17, 2020 Share Posted May 17, 2020 Interesting. I would say scute, but not my area of expertise. The only time I have seen mineralized fibers on the underside of an osteoderm are on from Upper Triassic Pseudosuchians. @jpc 1 Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...
jpc Posted May 17, 2020 Share Posted May 17, 2020 Those are some pretty tough photos to work with. I have seen the texture seen in the second photo in croc scuutes as well as ankylosaur scutes and ceratopsian frill pieces. 2 Link to comment Share on other sites More sharing options...

Raptor9468 Posted May 19, 2020 Author Share Posted May 19, 2020 Just for those who want to see the bone structure 1 Link to comment Share on other sites More sharing options...
Raptor9468 Posted May 21, 2020 Author Share Posted May 21, 2020 This might be a dumb question but Does ceratopsian have mineralized fibers ln the exterior of their bones? Are juvenile creatures common in fossils? Sorry for bothering but I've had trouble finding anything that looks like this with thickness under 1cm.

I haven't seen mineralized fibers like this on ceratopsian bones nor have I've seen a juvenile. I have only dug in the Lance Formation twice and prepped a few bones in the lab. @jpc and @Troodon are the ones to talk to. I wonder if the ornamentation sometimes seen on the edge of some juvenile ceratopsian frills might be thin like that. Jack Horner did an interesting TED Talk on the subject of juveniles that may interest you. 2 Lori www.areallycrappystory.com/fossils www.facebook.com/fossilpoo Link to comment Share on other sites More sharing options...
