fossils

Earth’s history is divided into unequal time intervals.  The boundaries between the intervals mark significant geological (very early Earth) or evolutionary events on Earth’s history.  Example: The boundary between the Precambrian eon and the Phanerozoic eon is marked by the rapid evolution and diversification of organisms with hard body parts.  The time intervals are eons, which are subdivided into eras.  The eras are subdivided into periods.  The periods are further subdivided into epochs (not shown on figure).   What is our current eon ______________, era _______________, and period _______________   Age boundary between the Hadean eon and Archean eon __________________   Age boundary between Archean eon and Proterozoic eon __________________   Age boundary between Proterozoic eon and Phanerozoic eon ________________   Age boundary between Paleozoic era and Mesozoic era ____________________   Age boundary between Mesozoic era and Cenozoic era ____________________   What…

Mammals quickly diversified into their various recognizable forms (i.e. cats, dogs, bears, ocean dwellers, rodents, etc) during the Period, just after the dinosaurs went extinct. Neogene Paleogene Quaternary Cretaceous

The largest and most deadly of all Mass Extinctions in the history of Earth came at the end of the Period, when only 5% of the existing species survived. Nobody knows exactly what caused this event, so it remains a mystery to this day. Quaternary Devonian Ordovician Permian

Can someone help me with this worksheet below and be very specific with the answers to the questions?

According to Scottish geologist Charles Lyell, the Cenozoic Era (including the Eocene, Miocene, and Pliocene epochs) extended over which of the following time periods in the fossil record? the Paleozoic Era, from the start of the Cambrian into the Permian Period the “age of reptiles”, from 252 million years ago to 66 million years ago the “age of birds and mammals”, from 66 million years ago to the present day the “age of fishes”, from 541 million years ago to 252 million years ago the Mesozoic Era, from the start of the Triassic into the Cretaceous Period

The field of geology helped to set the stage for the Theory of Evolution through an understanding that life on Earth is millions of years old erosion can reveal ancient strata of sediment fossils of ancient life can be found in these ancient strata of rock all of the above OO OO

After the Great Dying, we enter the Era which covers the evolutionary history of the dinosaurs up until they go extinct. Cambrian O Mesozoic Paleozoic O Cenozoic
