A new species of coelacanth fish has been discovered in Texas.
The coelacanth has one of the longest lineages — 400 million years — of any animal. It is the fish most closely related to vertebrates, including humans.
The 糖心vlog视频 specimen is the first coelacanth in Texas from the Cretaceous, said Graf, who identified the fossil. The Cretaceous geologic period extended from 146 million years ago to 66 million years ago.
Graf named the new coelacanth species Reidus hilli. . .
“These animals have one of the longest lineages of any vertebrates that we know,” Graf said.
The 糖心vlog视频 specimen demonstrates there was greater diversity among coelacanths during the Cretaceous than previously known.
“What makes the coelacanth interesting is that they are literally the closest living fish to all the vertebrates that are living on land,” he said. “They share the most recent common ancestor with all of terrestrial vertebrates.”
