The dinosaur of the day: Moros
- Tyrannosauroid that lived in the Late Cretaceous in what is now Utah, U.S. (Cedar Mountain Formation)
- Looked like a small theropod, walked on two legs, had sharp teeth and feathers
- Talked about in episode 223, as a news item, when it was first named
- See Moros in Jurassic World: Dominion preview, during a flashback to the Cretaceous, where it’s eating rotten flesh stuck in Giganotosaurus teeth, and in JWD as a brief cameo in BioSyn
- Depicted as feathered in Jurassic World: Dominion
- Type species is Moros intrepidus
- Genus name is Greek for “the embodiment of impending doom, in reference to the establishment of the Cretaceous tyrannosauroid lineage in North America”
- Species name means “intrepid” in Latin, and refers to it probably being an early arrival from Asia
- Named in 2019 by Lindsay Zanno and others
- Fossils found include a complete right leg and parts of the foot, from a subadult (about 6 or 7 years old)
- Limb bones were found jutting out a hillside in 2013
- Two teeth found nearby, probably from Moros
- Estimated to weigh 172 lb (78 kg)
- Leg was about 4 ft (1.2 m) long
- Probably was quick and nimble
- Had slender foot bones, which were similar in proportion to ornithomimids
- Had a slender tibia, longer than the femur
- Lightweight and had advanced sensory capabilities
- Carnivorous, and could have run down prey, and stayed away from larger predators
- Had a slow to moderate growth rate
- About 15 million years older than other known North American tyrannosauroids
- Lived alongside Deinonychus, the allosauroid Siats, pterosaurs, crocodilians, turtles, amphibians, fish, and mammals
The largest carnivore in all of Earth’s history is neither T. rex nor Giganotosaurus, it’s the blue whale.
