Richardoestesia isosceles was a theropod dinosaur genus, and thought to be in the Troodonidae family.  This a late Cretaceous dinosaur that lived from the Campanian to Maastrichian (70 to 66 MYA). So, they were present in the Judith River and Hell Creek Fm. Teeth have been found, but not much else to describe this theropod. Note - Richardoestesia teeth are typically found with Paronychodon teeth and they may be related much like the recent Sauronitholestes & Zapsalis teeth description (where Zapsalis in the Judith River Fm. is now described as the Sauronitholestes premaxillary tooth).
