Sturgeons are said to be long-living fishes as they reside near the water body’s surface and are often referred to as living fossils because they have been in a sort of similar form from almost hundreds of millenniums.

In a research conducted by Jack Stack, who is a graduate from the University of Pennsylvania and Lauren Sallan, who is a paleobiologist from Penn’s School of Arts and Sciences, in the Zoological Journal of the Linnean Society carefully researched on Tanyrhinichthys mcallisteri. It is an ancient breed of fishes which existed about 300 millenniums ago in a firth which is nowadays New Mexico. With that same jut snout, they are said to be very similar to sturgeons biologically. This tells that nowadays sturgeons have evolved from Tanyrhinichthys mcallisteri as they have inherited some qualities of theirs.

Another thing found was that different species of ancient fishes had no morphological similarities to Tanyrhinichthys nor they had any similar type of breeds. It was also found that sturgeons also weren’t an evolution of Tanyrhinichthys. Researchers came to know that long spouts were a sign of merging evolvement or many other fish species adopting the innovation to have adaption to their habitat. It showed that various living beings nowadays have their connections to past beings.
