fossils found in tar
The La Brea Tar Pits (or Rancho La Brea Tar Pits) are a cluster of tar pits around which Hancock Park was formed, in the urban heart of Los Angeles. Asphaltum or tar (brea in Spanish) has seeped up from the ground in this area for tens of thousands of years. The tar is often covered with water. Over many centuries, animals that came to drink the water fell in, sank in the tar, and were preserved as bones. The George C. Page Museum is dedicated to researching the tar pits and displaying specimens from the animals that died there. The La Brea Tar Pits are now a registered National Natural Landmark.

All or part of an organism becomes encased in amber (petrified evergreen tree sap), Ice (glaciers), Or tar (Rancho La Brae Tar Pits of Los Angeles)
Petrified fossils are organisms preserved I'm other substances such as amber, tar, ice, or other substances
original remain is organisms encased in amber and i dont know if you can find it in tar
It seals off bacteria, air, and many other things that can cause organisms to decay. If the organism doesn't decay, it remains for... well, forever. As long as it doesn't leave the tar, however! :)
Amber, Permafrost, and Tar.
Preserved remains are formed when the body of an organism is preserved and protected from decay through freezing, being trapped in tar, sap from a tree hardens around the body, or the body is put in a bog. (Like a peat bog.)
