Salmon fossils are found more often than stingray fossils because:

there were more salmon than stingrays
salmon died more often than stingrays
cartilage is softer than bone and does not preserve well
stingrays have hollow bones that do not make good fossils

Fish fossils are usually divided into two main groups. One group includes fish with true bones, like salmon, bass, and goldfish. Scientists have found true bone fossils that are over 360 million years old. The other group includes fish with skeletons made of cartilage. Sharks, eels, and stingrays belong to this group. Most fish fossils are from species with true bones. Cartilage is softer than bone, and does not preserve as well.

this is from my school work assignment this is the correct answer, hope this helps!!!!!!
