Just some pieces of the skull, but its fragmentary nature aside, this is great to have for learning more about the prehistoric ecosystem at the time this lived in and possibly shared it with.

Awesome art by Julius Csotonyi of course.

..and the TINY companion is Timurlengia.  Now I'm really curious about the "realistic" interactions between Carcharodontosaurids and Tyrannosauroids (where they overlapped).  Were they like modern cats and dogs (ie extremely antagonistic towards each other, actively testing territories and hunting offspring) or more like sympatric crocodilians (ie: I'll only hunt you down if you're within striking distance, or I'm starving)?

Sadly, if the creature itself is from scrappy fossils, what are the chances of finding fossilized evidence of behavior?

I always also thought about that comparison.  Carcharodontosaurs being similar to dogs, once having gigantic predators, but now those roles belong to cats. Only difference is that when dogs switched from Megafaunal predator to fast intelligent predators they became even better
