“Big things have small beginnings.”
The Tyrannosaurs have always been one of the most iconic family of dinosaurs ever to walk the Earth. However, their ancestral evolution largely remained a mystery until recently. Two years ago, the earliest ancestor of the Tyrannosaurs was discovered. This animal was no larger than a deer and was built for speed. Its name became Moros intrepidus, which means “harbinger of impending doom”, which is a fitting name considering what this creature’s descendants would one day become. Due to this discovery, experts theorize that Moros intrepidus lived in the shadow of larger carnivorous dinosaurs such as the carnosaurs. However, when the large theropods fell into extinction, Moros intrepidus and its kin wasted no time filling the power vacuum. Over the course of 16 million years, this one small predator evolved and diversified into over a dozen species of powerful predators including Tyrannosaurus Rex itself. This goes to show that even the mightiest of beasts come from the humblest of origins.
