- Fossils give us clues about how life was in the past. ]]> 2019-03-12 01:15:00 UTC https://padlet.com/jdrewett/zqc92nby0yd8/wish/340218604 Geological Time jdrewett https://padlet.com/jdrewett/zqc92nby0yd8/wish/342654565 -How long ago were the animals on earth? 66 million years ago dinosaurs were wiped out. In 1975 dinosaur bones were found in NZ, near the Hawke's Bay.

- Are there people mentioned in the stories? Why not? There were no people because it was 66 million years ago and human was living then.

- If there were no people, how do we know about the animal?  We know about dinosaurs by all the fossils and footprints found in the land.]]> 2019-03-19 00:44:15 UTC https://padlet.com/jdrewett/zqc92nby0yd8/wish/342654565 Why are fossils relatively rare? jdrewett https://padlet.com/jdrewett/zqc92nby0yd8/wish/345942332 Living things rot away and disintegrate after they die unless something happens to preserve them.
Very few things survieve as fossils after they die.
Less then 1% of thing that die turn into fossils. Preserved means the remains became buried within some medium that prevents them from being further destroyed through natural decay or predators.]]> 2019-03-28 00:44:02 UTC https://padlet.com/jdrewett/zqc92nby0yd8/wish/345942332 Main Agents that cause Decay. jdrewett https://padlet.com/jdrewett/zqc92nby0yd8/wish/345948538 Oxygen, Predators, Microorganisms,Radiation, Weather/Erosion.]]> 2019-03-28 01:06:29 UTC https://padlet.com/jdrewett/zqc92nby0yd8/wish/345948538
