Mammal found with teeth sunk in a much larger dinosaur

perhaps it was: https://en.wikipedia.org/wiki/Osteoblast
The second thing that I noticed is that the bones from both animals lie too close (in my non expert opinion, could be wrong). If somebody grabs a leg with its hand, there is muscle and skin in between. Is expected that the phalanges would remain a little apart from the femur. In the fossil it seems that there is not any space in between. I wouldn't discard the case of a scavenger biting a partially skeletonized body but in that case its arms and legs would lie in different positions.
That dinosaur beak could also chop that hand probably. Why is entire?. I don't see any of the expected results of such fight. No broken bones in the mammal it seems. That would happen only if the mammal was poisonous and an insta-killer, but nothing suggests that.
And not a single bone crushed or broken by the pressure of the sediment it seems. Not one missing.
Is... I wouldn't say fake, but very weird for sure.
In retrospect, maybe this should not have surprised me, but hey, TIL.
