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.

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.

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.
