Answer:
I can’t comment but most of the other persons answer are wrong.
Here are my answers:
-an original-remains fossil
-amber, bone, tooth, shell
-decease exposure to oxygen, slows down the rate of decay, prevents scavengers from eating organism remains
-stable geological conditions, rapid burial, presence of minerals
-their closest living modern relatives, their potential evolution, their age at death
- idk it’s not dinosaur fossils or insects trapped in amber
-worms once lived in the area
