When do small mammals appear in fossil records?
During the KT extinction event the majority of life on earth became extinct. Small mammals, however, were able to survive this mass extinction.
What is the name for the modern era which began approximtely 65 million years ago with the mass extinction of the dinosaurs?
The Cretaceous period ended with the extinction of the dinosaurs. The period that followed the mass extinction was called the Paleocene. This was a time of the mammals.
What are mass extinctions followed by?
Mass extinctions are usually followed by long periods of low or absent population. Some species always survive a mass extinction, following the Darwinian law of survival. When the dinosaurs died out the mammals began to prevail and eventually took over.
What type of reptile did not survive the mass extinction event at the end of the mesozoic era?
Dinosaurs
What effects have mass extinctions had on history life?
Mass extinctions have the effect of eliminating a large number of species, which leaves a wide variety of niches open to new species. Whichever species survive the mass extinction quickly evolve into many new forms to fill the empty niches. The Permian-Triassic Extinction Event left niches open to the dinosaurs, and the Cretaceous-Tertiary Extinction eliminated dinosaurs, leaving niches open to mammals.
How does mass extinction affect species that survive?
Every animal is a part of the food chain, so mass extinction can have very bad consequences for the species that survive. The surviving species must learn to work around the animal that has recently become extinct.
What is the effect of mass extinction?
The effect of mass extinction is extinction, death of a mass
How might the mass extinction at the end of the mesozoic era relate to the dominance of mammals in the Cenozoic era?
mass extinction: When at least 50 % of the species on Earth go extinct within a relatively short amount of time.
How mass extinction affected life on Earth?
Mass extinction isn't a natural role in any life-system. They happen as a consequence of some catatrosphic disaster or radical unbalance in the eco-system. As a result of mass extinctions other 'groups' evolve into species that take the place of those exterminated.
What are the extinction of animals in the very distant past?
There were five major extinction events in the past. They are called the Cretaceous-Tertiary (or K-T) extinction event, the late Devonian mass extinction, the Permian mass extinction, the Ordovician-Silurian mass extinction and the Triassic-Jurassic mass extinction event.
Did no acient animals survive?
Yes, some ancient animals survived the mass extinction primarily by living underground or underwater.
What is the mass extinction?
the holocene extinction
