Question

A scientist finds fossae on a bone sample. what can the scientist conclude?

Answer 1

Fossae are holes or depressions in the bones that are usually found on the end of the long bones. Fossae are good indications that a bone was connected or articulated with another bone. Therefore, if a scientist has found a fossa on a bone he or she could conclude that the bone was joined with another bone in the skeleton at the place of the found fossa. 

Answer 2

This bone was near blood vessels or organs.
