It is the final period of the Mesozoic era.
On the geologic time scale, an era is longer than a period. There are 12 geologic eras in total and they are composed of geologic periods. For instance, the Mesozoic era is composed of the Triassic, Jurassic and Cretaceous periods.
It was part of the Mesozoic Era.
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.
The Paleogene Period followed the Cretaceous.
No, a geologic era is a longer unit of time than a geologic period. Geologic eras are divided into periods, which are further subdivided into epochs. The hierarchy from largest to smallest is era, period, epoch.
The two basic divisions following the Precambrian on the geologic time scale are the Paleozoic Era and the Mesozoic Era. These eras are further divided into periods, such as the Cambrian, Devonian, and Permian in the Paleozoic Era, and the Triassic, Jurassic, and Cretaceous in the Mesozoic Era.
mesozoic
Mesozoic Era
The Paleocene, which is the first (oldest) part of the Cenozoic Era, as the Cretaceous was the last of the Mesozoic Era.
That is easy, the first is precambrian time, next you get the paleozoic era, which has Cambrian, ordovician, silurian, denovonian, carbonferious periods, Next you get the mesozoic era which contains the next three, which are triassic, jurrasic, and cretacous periods. Lasty you get the Cenozoic era which contains the last two which are the tertiary, and the quaternary!
I know that the angiosperms were most dominant during the cretaceous period but im not too sure about the dinosaurs dominant era. I would assume they were both dominant in the same era but I am not 100% sure.
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.
