Frilled you made it after all these years

A dinosaur era frilled shark (same species fossil remains dated to the dinosaur/Cretaceous age) has been captured and then examined by scientists.

Referred to by the Portuguese scientists as a 'living fossil' the frilled shark has remained virtually unchanged since this species shared the planet with dinosaurs. Remains of Chlamydoselachus anguineus have been dated back 80 million years to the Cretaceous period when Tyrannosaurus Rex and Triceratops still ruled the Earth.

This prehistoric shark’s most striking feature is its unique mouth, sporting more than 300 teeth displayed in a frilled, or ruffled, arrangement over 25 rows.

... Another primitive trait of this ancient deep-dweller, is the fact that frilled sharks have either six or seven gill slits — unlike all the other shark species, which only have five.

Prehistoric sharks life alive today

Interpretations:

  • The shark has survived 80 million years and all the planetary catastrophes, mass extinctions and changes to the oceans
  • Virtually no genetic changes in 80 million years yet most environmental conditions and lifeforms have altered
  • Nature uses similar basic building blocks to create life appropriate to the environment of that era, no convergent evolution
  • Dating issues - dating techniques not reliable
  • Chronology revisionism - dinosaurs were still alive not that long ago or their era was not millions of years ago
  • Other?

Chlamydoselachus anguineus living dinosaur

The frilled shark is found across the Atlantic, including off the coast of Norway and in the waters of Scotland, Galicia in Spain, the Azores, Madeira and the Canary Islands, as well as in the Indian and Pacific Oceans, namely off Japan, Australia and New Zealand. It is rarely caught because it lives at great depths.
