So much going on in the sea, air, and land. It’s the period that most dinosaur media focuses on, including Jurassic Park (ironically as the jurassic is a different period) and Prehistoric Planet. Includes Tyrannosaurus, Utahraptor, Triceratops.
What evolutionary developments occured during this time?
Starting with rotten flesh-smelling plants.
Need a bit in here about the Cretaceous climate.
What role did it play in its ecosystem?
What’s something interesting about it?
The evolution of Tyrannosaurus
Mosasaurs (from Latin Mosa meaning the 'Meuse river', and Greek σαύρος sauros meaning 'lizard') are large, extinct, marine reptiles. The first fossil remains were discovered in a limestone quarry at Maastricht on the Meuse in 1764. Mosasaurs probably evolved from semiaquatic squamates known as aigialosaurs, which were more similar in appearance to modern-day monitor lizards, in the Early Cretaceous. During the last 20 million years of the Cretaceous period (Turonian-Maastrichtian), with the extinction of the ichthyosaurs and decline of plesiosaurs, mosasaurs became the dominant marine predators. -Wikipedia, Mosasaur
