Some of the earliest flowering plants were also found here. Rivers and streams coming down from the flanks of the volcanoes fed into lakes in the valleys. [citation needed] There were many species of small birdlike theropod dinosaurs living in the area, although most of them were slightly larger than Mei. This probably led to a lot of niche ...

It currently contains a single valid species , Pectinodon bakkeri (sometimes classified as Troodon bakkeri ), known only from teeth.
However, there are exceptions, like an ornithomimid caudal vertebra that has tooth drag marks attributed to Saurornitholestes and a partial Troodon skeleton with preserved puncture marks. [8] Small bones of small theropods that were preyed upon by larger ones may have been swallowed whole and digested frequently enough to affect their abundance ...
One of the coolest, most prehistoric-looking fish lives in Florida’s offshore waters of the Gulf of Mexico. It happens to be one of the best to eat but also one of the most elusive.
Troodon eggs continued to attract scholarly attention in the 1990s. 1996. Darla Zelenitsky and Leonard Hills described the eggs of Troodon formosus. They found that the surface of Troodon eggs were smooth and their pores occurred singly or in pairs. When viewed in thin section, the eggshell exhibited two distinct layers.
