Now, this enormous ancient fish is officially extinct. This fish has largely remained unchanged for the past 200 million years. It grew to seven metres in length.
While the dates are spurios , they nevertheless say that the fish is old.
"The last of the fish likely died between 2005 and 2010, the researchers will report in the March 2020 issue of Science of The Total Environment",
