Suppose you find a rock with a goniatite fossil and another rock with an ammonite fossil? Which rock is older? How do you know?

Biology

Goniatite: 390-400million years old

Ammonite: 65-66 million years old

Since ammonites are usually food to the tylosaurus, (existed 66 million years ago) you could estimate ammonites are 65-66 million years old.

And for goniatites, all I know is that it’s from the Devonian period

Why should/shouldn't Pluto be reclassified as a planet?​
Scorpion4ik [409]

Answer:

(This could be opinion based, but ok.)

Explanation:

should:Pluto was known as a planet for 75 years. This means that most people already knew it as a planet, and would be extremely confused. All of the books about planets would be inaccurate and changed. Not all people can access brand new books, leading to inaccurate information.

shouldn't: The same reason that it was unclassified as a planet. It does not adhere to all of the rules of being a planet. It is not completely round and does not have a round orbit around the sun. Pluto does not have every requirement to be a real planet, and therefor, it would be incorrect to have it classified wrongly.
