My Jurassic Park - Injured, Predation or Diseased Dinosaur Bones

[roostarr]

These are fantastic, always interesting to see fossilised proof of injury, damage and recovery.

[Troodon]

Have not added much recently to this topic so here are several new ones

 

Carpals of Trex are super rare here is one with some pathology by the joint.

 

 

Arthritic joints appear to be common with Dinosaurs.  Here is a carpal on a Spinosaurid that must have been painful hand from an older animal

 

 

 

Pretty good evidence of predation on both sides of this juvenile Edmontosaurus dorsal centrum

 

[Guns]

Could this also be a predation mark or just a damage from excavation ?

 

tooth mark ??

 

compressed 

[Troodon]

Difficult to say lean more toward it not being being predation.   I dont see that being a tooth puncture considering how fragmented the area around it looks like.  Compression is typical of other vertebrae.
