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! :)
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.
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.
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).
Dinosaurs lived in this period as well there are some plants like flowers and grasses.
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.
Yes, amphibians, primitive mammals, birds, fish ammonites etc.
yes
there were bugs and reptiles (lizards, crocodiles etc)
Flying animals and swimming animals existed before land walking animals.
Well,the dinosaurs your probably thinking of is like T-Rex's and others but there actually is a dinosaur that is still alive...Crocodiles,turtles,some fish and more!
There aren't any dinosaurs alive any more anywhere
no animals have a brain even dinosaurs do
Yes, there undoubtedly were, just as today there are some animals that are much more common than others. the scillopogosarus
Dinosaurs are not alive any more but there are relatives of them such as birds as distant cousin.
The dinosaurs are technically alive anyway since birds are dinosaurs. There is currently no evidence that any non-avian dinosaurs have survived past the mass extinction around 65million years ago.
Yes. Many scientists nowadays consider birds to be dinosaurs. Animals such as pterodactyl were not actually dinosaurs.
Dinosaurs are not alive any more duma$$
Crocodile is an ivolved dinosaur if that's any help
yes, birds are related to them.
No because dinosaurs lived more than a billion years ago.
Define dinosaur. Dinosaurs were the dominant vertebrate animals of terrestrial ecosystems. Meaning they only lived in land. The ones that live in water are other reptiles but certainly they are not dinosaurs.There were numerous prehistoric reptiles that were aquatic, such as the ichthyosaurs, plesiosaurs and mosasaurs, that were alive during the time of dinosaurs.
