no fossils of organisms with hard parts. the few soft body part fossils found rarely fossilize well.

Quaternary.
ok im going to start off by saying this, the last answerer is stupid, and doesnt know what he is talking about. it goes from: PERIOD ERA EPOCH there you go ;)
Earthquakes and Volcanoes,extinctions of dinosaurs,tsunamis,the breakup of Pangaea the super-continent and many other things

It is difficult to interpret recent history and current events because there are numerous and variable interpretations of events and their significance. Historical research is not an exact science, so it may not be possible to uncover what actually happened. It is also difficult to see a recent or current event from an historical perspective.
Quaternary.
Smilodon lived in a geological era recent enough in history that the atmosphere would have been virtually the same as it is today.
The correct order of the four major geologic eras from oldest to most recent is Precambrian, Paleozoic, Mesozoic, and Cenozoic.
The Cenozoic era
The 4 eras are Cenozoic era, the mesozoic era, the paleozoic era, and the precambrian era.
The most recent Ice Age
There will be few impact craters.
There are so far 4 Eras in the earths history. the one that started the beginning if the earths history: Precambrian Time. The one after that was the Paleozoic Era, which means "ancient life." next was mesozoic which means "middle life" the one we are in is called the Cenozoic Era which means" recent life." * All Eras ended with a mass extinction.
