Hell Creek is T. rex country, so it is a nice change to meet a 12 kg neighbour with a weak bite and a sliding jaw that probably preferred fruit. The comparison to a living parrot is the bit that makes it click. Also a reminder that a nearly complete skull can sit in a collection for over a decade before its story gets told.

Forensic palaeontology at its finest: researchers measured serration spacing in bite marks, corrected for the angle of the bite, and named a likely suspect. The size gap makes the case, since a turkey-sized raptor was not taking down a half-tonne tyrannosaur, but it would happily clean up after one.

Not every dinosaur find is a skeleton; sometimes it is one 37 mm bone that moves a timeline by tens of millions of years. Worth noticing how much careful phylogenetic work can hang on a single centrum, and how honest the authors are about not naming it.

Proof that the best fieldwork sometimes happens in a storeroom. A scrap of skull the museum bought in 1924 turns out to be the first megaraptoran ever found in Europe, which redraws the map for a whole family of big-clawed hunters. Bonus points for a name that translates as unconquered female warrior.
