What types of animals lived in the lowland forests 65 million years ago?

During the late Cretaceous period approximately 65 million years ago, the lowland forests were teeming with a diverse array of animals. Among them were the dinosaurs, the dominant land animals of the time. The forests were home to a variety of herbivorous dinosaurs, such as the Triceratops, Stegosaurus, and Hadrosaurus. These dinosaurs fed on the lush vegetation of the forests, and they were in turn preyed upon by carnivorous dinosaurs, such as the Tyrannosaurus rex and Velociraptor.

In addition to dinosaurs, the lowland forests were also home to a variety of other animals, including mammals, birds, amphibians, and reptiles. The forests were home to some of the earliest mammals, such as the Multituberculates and the Marsupials. Birds were also present, and they were likely descended from small, feathered dinosaurs. Amphibians and reptiles were also common in the forests, and they included frogs, salamanders, lizards, and snakes.

The lowland forests of the late Cretaceous period were a vibrant and diverse ecosystem, home to a wide range of animals. These animals played important roles in the functioning of the ecosystem, and they helped to shape the world that we live in today.
