Hello Reader, Writers, Teachers, and Children! Our earth is somewhere around 4.5 billion years old. And living things have existed on it for maybe 3.5 billion years. But humans have only been around for some thousands of years. Think of all that we’ve missed!
Dinosaurs, mega sharks, giant sloths, huge ferns, and really, really weird critters! New fossils are discovered every day. With each new discovery, we learn a little more about our past. In this article series, we will talk about the following periods and the plants and animals that lived during those times:
| Archean | Permian |
| Proterozoic | Triassic |
| Cambrian | Jurassic |
| Ordovician | Cretaceous |
| Silurian | Paleogene |
| Devonian | Neogene |
| Carboniferous | Quaternary |
The first two sections, Archean and Proterozoic, cover portions of time known as eons. The other sections are periods that fall under the Phanerozoic Eon, which covers the time from 541 million years ago to today.
These articles will be written at about a Grade 5 reading level. I’ll do my best to make them fun and interesting to read at any age!
By the way, did you know that Tyrannosaurus Rex lived during the Cretaceous Period? I guess Cretaceous Park just doesn’t have that ring to it.
