identify any two fossil specimen on the basis of morphological characters
Answers
Morphological Traits: changes to the outward appearance of an animal as well as the form and structure of internal parts, like bones and organs. Example: Snowshoe hare is more than prepared for the winter environment with large back feet for easy travel and a white coat for camouflage.
Explanation:
It is a sad fact of life that jellyfish rarely fossilize. Being squishy, and without a hard backbone to preserve, jellyfish and their like are very rare in the fossil record. In fact, for most fossils, the only bits that paleontologists have are their hard parts, such as bones, shells, and scales. There are certain rare examples of soft-tissue fossilization, and most of these occur in areas of exceptional preservation called lagerstätte (German for storage place), like the example of the soft-bodied worm Ottoia preserved perfectly in the Burgess Shale, a Cambrian lagerstätte.
The shape of these fossilized body parts, whether they're hard or not, is called their morphology and is used to help distinguish one species from another.
