A midnight testing theory

Coming from Late Cretaceous Madagascar, this was the largest frog to ever exist, growing up to the size of a dinner plate. Much like modern frogs, this ‘devil toad’ would have been a predator, and its size would have enabled it to feed on a wide variety of small animals, including baby dinosaurs.

Oviraptor the ‘’egg stealer’’ that lived in Mongolia during the late Cretaceous. I watched a documentary not that long ago that Oviraptors might not be egg stealers but rather verry protective over thir eggs. You can watch it here

Hailing from Brazil during the Early Cretaceous, this spinosaurid's name derives from the fact that it's nearly complete skull had been heavily damaged and altered by the collectors who found it (along with a reference to Professor Challenger in Sir Arthur Conan Doyle's The Lost World. ). Based on the remains we do have, Irritator leans on the smaller side for spinosaurids, estimated to be between 20 to 26 feet long. At the same time, though, the specimen was found to be a juvenile, so it potentially grew to be much larger as an adult.

Dating back to the Late Cretaceous (and possibly right up to the end of the period), Hesperornis was a flightless, cormorant-like bird that measured up to 6 feet long. It was a marine creature, swimming in the Western Interior Seaway that stretched from Canada, through Kansas, and into Mexico, and had to deal with all of the other marine horrors that swam through there as well. Being on the small side in this nightmare aquarium, Hesperornis survived by being agile in the water, while keeping itself sustained with a beak lined with needle-sharp teeth. Unlike penguins, it wouldn't have been able to walk on it's hind legs, and probably hauled itself on it's belly onto shore like a seal.
