What is the significance of the boundary between the cretaceous-tertiary time periods?
The boundary between the Cretaceous and Tertiary periods, known as the K-T boundary, marks a significant mass extinction event that wiped out the dinosaurs and many other species. It is believed to have been caused by a combination of factors, including a meteor impact and volcanic activity. The extinction event paved the way for the rise of mammals and ultimately led to the diversification of life on Earth.
What era did earth contain a layer of iridium?
The layer of iridium that is found in the Earth's crust is associated with the Cretaceous-Paleogene (K-Pg) boundary, which marks the end of the Mesozoic Era and the beginning of the Cenozoic Era. This layer is often linked to the mass extinction event that led to the extinction of the dinosaurs.
Why would a dinosaur with feathers be a bad index fossil?
Dinosaurs with feathers have been found through a relatively wide range of geologic time. Not counting birds feathered dinosaurs can be found from the Jurassic period to the end of the Cretaceous period.
Which era contains fossils of dinosaurs?
Dinosaurs lived during the Mesozoic Era, which is divided into three periods: Triassic, Jurassic, and Cretaceous. Fossils of dinosaurs have been found primarily from the late Triassic to the end of the Cretaceous period.
What dinosaurs lived in Kenya?
A number of dinosaurs are known from the Tendaguru Formation of Tanzania. Kenya may have been covered in a shallow sea at the time, but if it wasn't, the dinosaurs in Tanzania and Kenya would have been the same. These include Kentrosaurus, Giraffatitan, Dysalotosaurus, Dicraeosaurus, Allosaurus, Ceratosaurus, and Elaphrosaurus. They lived around 150 million years ago.
What exclusive element was found at the cretaceous tertiary boundary?
Iridium

How did humans discover what dinosaurs lived in the cretaceous time period?
they found the bones and fossils of the dinosaurs

How did dinosaurs hatch their eggs?
Fossil dinosaurs nests have been found with dinosaurs sitting on their nests like birds do. This is not surprising as our modern day birds are descended from raptor dinosaurs.
What dinosaur was found in Maine?
No dinosaurs have been found in Maine. The state fossil is Pertica, a plant from the Devonian.
Can dinosaurs be pets?
Technically yes. While dinosaurs are generally regarded as extinct by the public, it has been found that birds are, in fact, the only dinosaurs to have survived the Cretaceous-Paleogene extinction. So if you have a pet bird, you have a pet dinosaur.
What vegetables would be found in a dinosaurs habitat?
None, because there were no flowering plants except in the middle Cretaceous and late Cretaceous, which means only 2/9 of the dinosaur time there were flowers but no vegetables or fruits.
