A video of a frilled shark is being shared online with claims that it is 80 million years old. The frilled shark is sometimes called a living fossil due to its lineage that goes back 80 million years. A Twitter post of the video (here ) with the description “Prehistoric 80 million year old shark also known as “the frilled shark” discovered in Awashima, Japan” posted on Oct. 14, 2022 had over 7.8 million views as of writing. A copy of it can be seen (here ), and it shows the same video seen in the posts being shared. However, a frilled shark has a lifespan of about 25 years, as discussed ( here ) and its lineage goes back almost 100 million years (here ).
