There were far too many organisms in the Mesozoic that have been discovered to list, and what has been discovered is only a fraction of what actually existed. Here is the list for you:
Animals
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)
Plants
Ferns and Tree Ferns
Conifers
Cycads
Bennettitales
The first angiosperms (flowering plants) appeared during the end part of the Cretaceous
What else can I help you with?
When did Acanthoscaphites live?
They lived during the Cretaceous time period at the Mesozoic era.
Toothed birds lived in which Period of geologic time?
Toothed birds lived in the Mesozoic Era during the Cretaceous Period, specifically in the Late Cretaceous. They were among some of the earliest birds that evolved before losing their teeth as part of their adaptation for flight.
In which era did the dinosaurs exist?
Mesozoic but it was split into 3- Triassic, Jurassic and Cretaceous. Dinosaurs lived from the late Triassic Period, Jurassic Period and Cretacious Period. Dinosaurs died in the Late Cretacious Period 65 Million Years Ago
Which period is older than the Triassic period?
The Jurassic Period followed the Triassic.
What time period did triceratops dinosaurs live?
Triceratops existed from 68 to 65.5 million years ago. That was at the end of the Maastrichtian stage, the last stage of the Cretaceous period, which was the last period of the Mesozoic. In fact, Triceratops existed at the very end of the Mesozoic era and was one of the dinosaurs wiped out by the K-T extinction.
Dinosaurs lived 230 million years ago during what era?
The dinosaurs, those giant lizard creatures, dominated the face of Earth for about 165 million years. This period of time is called Mesozoic Era, and during this time the planet suffered several violent changes.
What were the beginning events for the mesozoic time period?
dinosaurs
What time period did the pentaceratops live in?
In Mesozoic Era .
What time period did the ankylosaurus come from?
Ankylosaurus lived between 66.5 and 65.5 million years ago. That was during the end of the Maastrichtian stage, the last stage of the Cretaceous period, which was the last period of the Mesozoic era.
Jurassic is the period of what era?
It really wasn't an era. An Era was a much longer period of time. It was called the "Jurassic Period".
In which time period did the dinosaurs mainly live?
Mesozoic Era
What type of animal lived only during mesozoic era?
The type of animal that lived only during the Mesozoic Era (Age of Reptiles) were the dinosaurs. They evolved during the late Triassic and the Jurassic periods, and were the largest land creatures during the Cretaceous period of the era.
