Were there any others animals when the dinosaurs were alive?

Answer 1

There were far too many types of animals to list them all, but here are a few:

In the Air:

Insects

Pterosaurs

The first birds (some of which had teeth)

On Land:

Dinosaurs

Small mammals (multi-tuberculates, placentals, marsupials, and monotremes)

Lizards

Amphibians (frogs, salamanders, and the last temnospondyls [huge, toothed amphibians])

Insects

In the Ocean:

Fish

Coral

Sharks

Plesiosaurs (marine reptiles, some of which had long necks)

Icthyosaurs (marine reptiles that looked like fish)

Mosasaurs (huge marine lizards)

These are just the main categories of animals that lived during the Mesozoic. For individual types, you might want to research each individually. Hope this helps! :)

Answer 2

Dinosaurs were only a small part of the number of animal species which died at the end of the Cretaceous period. More than 50% of all species died at that time.

Not as large a percentage as died at the end of the Permian period.

Answer 3

Although dinosaurs made up the majority of large land animals, there were many other creatures. There were lizards, amphibians, and mammals. There were pterosaurs in the air and plesiosaurs and icthyosaurs lived in the seas. Crocodilians also existed. Fish existed, including sturgeon. Almost any invertebrate you could think of existed during the dinosaur age.

Answer 4

Yes. Flying creatures, like Pteranodon, and swimming creatures, like Elasmosaurus, weren't actual dinosaurs, despite the fact they lived during the Mesozoic Era (time of the dinosaurs).

Answer 5

Dinosaurs lived in this period as well there are some plants like flowers and grasses.

Answer 6

Yes, but only really small rat-like mammals.They lived with the dinosaurs from the Triassic to the Cretaceous periods. Didelphodon was one of them that lived in the Late Cretaceous.

Answer 7

Yes, amphibians, primitive mammals, birds, fish ammonites etc.

Answer 8

yes

there were bugs and reptiles (lizards, crocodiles etc)

Answer 9

Flying animals and swimming animals existed before land walking animals.
