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.
How was the cretaceous period different from the Jurassic period?
The Cretaceous period followed the Jurassic period and lasted from about 145 million to 66 million years ago. In the Cretaceous period, flowering plants became more dominant, dinosaurs continued to diversify, and large marine reptiles like mosasaurs thrived. However, the end of the Cretaceous period marked by a mass extinction event where dinosaurs and many other species went extinct.
What geological period did the protobalanus spinicoronatus live in?
Protobalanus spinicoronatus is a species of extinct planktonic foraminifera that lived during the Late Cretaceous period. This geological period spanned from approximately 100.5 to 66 million years ago. Fossils of this species have been found in marine sediments, indicating its presence in ancient oceanic environments during that time.

What appeared near the beginning of the Cretaceous period?
The most notable group of organisms that evolved at the beginning of the Cretaceous are the flowering plants, or angiosperms. Today, these are the majority of plants on Earth. All fruit bearing plants and grasses are angiosperms. At the same time as these evolved, new insects evolved that pollinated the flowers. Additionally, birds evolved either during the late Jurassic or the early Cretaceous.
What happened after the Jurassic period?
There was a decline in many species of plants and animals and new forms evolved, ushering in the Cretaceous Period with flowering plants and hardwood trees, along with the first true birds.
During which era did the mosasaur swim in the interior seaway?
probably during the early part of the Cretaceous Period
Toothed birds lived in which Period of geologic time?

Animals during cretaceous period?
Some animals during the cretaceous period were tapejara, microraptor, and velociraptor. There was also triceratops, styracosaurus, and the tyrannosaurus rex.
When was the time period of trex?
Tyrannosaurus lived during the Cretaceous Period.
What period did the spinosaurus live in?
Spinosaurus fossils have been found in Morocco and Egypt, and they date to between 112 and 97 million years ago. This was during the Albian and Cenemonian stages of the Cretaceous period, which was the third and final period of the Mesozoic era.
What dinosaurs lived in Mongolia in the late cretaceous period?
