*Fossils
Palaeontologists study fossils to learn about dinosaurs. Fossils are
dead animals or plants. Sometimes fossils are footprints or poo, small
animals or insects get stuck in tree sap which hardens and traps them
forever. They are usually skeletons found embedded in rock.

*Age of Dinosaur
Dinosaurs first existed 230 million years ago mya The time between
then (230 mya) and now (2019 AD), it split into different periods of time
. The Age of dinosaurs, also known as the Mesozoic Era, spans three
periods; Triassic periods (230-MYA).,Jurassic period (200-146 MYA)
and Cretaceous period (146-65 mya). Over this time different animals
evolved. 150 mya: Birds (avian) evolve from dinosaurs. Flowering
plants appear (140 MYA) , Snakes evolved from lizards (130 MYA) and
dinosaurs died out (65 MYA).

*What were the dinosaurs like?

main groups of dinosaur ,called theropod, sauropod, thyreophorans,
cerapods. They are also classed as avians and non-avian. So if you
didn’t know that modification means

dinosaurs to die. Scientists have two ideas about how this happened.
