Welcome to my free coloring pages blog.
Today's new drawing is of a young T. rex chick
and a Cretaceous mammal called Didlephodon.
Didelphodon was a 1-foot long mammal with a powerful bite for its size. It lived at the same time as T. rex or Tyrannosaurus rex. There is good evidence that Theropods like T. rex hatched and were cared for by their parents. This young Tyrannosaur must be only about 4 feet long.
I have witnessed, in Yellowstone National Park, a scene where ravens local wolf pack that there was an injured elk nearby. The ravens led the wolves to the elk. This type of relationship between species is called a symbiotic relationship. More specifically it is mutualism because both species benefit from the relationship. The wolves get a meal and the ravens get a meal of leftovers when the wolves are done.
I thought: What if Didelphodon and Tyrannosaurus rex had a mutualistic relationship? The Didelphodon pack could keep watch over the Tyrannosaur pack while the Tyrannosaurs slept. Then when a kill was made the T. rex could bring a bit of meat to the Didelphodon.
