USNM 4734 (incl. USNM 2315) anyone?

USNM 2315 is the type of Labrosaurus ferox_, which probably belongs to the _Allosaurus fragilis_ specimen USNM 4734. USNM 2315 compsrises a deformed left dentary, probably the result of injury. USNM 4734 shows broken gastralia, so not only did the poor allosaur get smacked in the face, but it also took one in the breadbasket.

Rather than a _Diplodocus_ whiptail being the culprit, maybe the allosaur fell foul of a stegosaur-style thagomizer?!
