Biosyn has a Moros intrepidus that can be seen in a glass enclosure when Doctors Grant and Sattler are touring the facilities. Watching it practice its hunting skills with a small mammal, they seem surprised to see that Biosyn has cloned it so quickly. The first Moros fossils were found in 2013, and the genus and species were only classified in February of 2019. Its scientific name means "harbinger of doom," and it was chosen because this small theropod was a sign of bigger, scarier things to come.
In the "Prologue" video, a Moros can be seen cleaning the teeth of a larger predator. In reality, these small but mighty dinosaurs evolved into large predators whose kind spread throughout the continent, and pretty quickly in the grand scheme of things. Paleontologists had long been puzzled by a 70-year gap in which no tyrannosaurs seemed to exist in North America. There were primitive ones from the Jurassic period and ones like the famous T. rex from the late Cretaceous, but nothing in between. Then, a team in Utah found Moros. Like T. rex, Moros lived in North America during the Cretaceous, but he predated his supersized relatives by about 15 million years and probably migrated over a land bridge from Asia, which explains a lot.
As explained by National Geographic, Moros is the missing link that is helping paleontologists understand how tyrannosaurs went from a few feet long to more than 40 feet long. The one depicted in "Jurassic World Dominion" might've been a little on the small side, but its proportions and feathering are probably pretty accurate. This adorably tiny predator was a killer and a survivalist. It was light, fast, and had strong senses with which it could catch prey and evade larger theropods.
