What is it about?
Our application of a recently developed geochemical analysis (dual clumped isotope thermometry) on fossil eggshells revealed that Troodon, a dinosaur with several bird-like characteristics, was warm-blooded like modern birds but produced its eggs in a way comparable to modern reptiles. Based on these results, we were able to determine that Troodon produced only 4-6 eggs per clutch and thus, the large Troodon fossil nest (with up to 24 eggs) were likely shared by multiple females.

Why is it important?
Understanding biology and behaviour of dinosaurs has always been a great challenge for palaeontologists because soft tissues (like skin or internal organs) are often not preserved. Our work revealed new information about both of these aspect for Troodon.
