New 20-million-yr-old extinct shark species identified
An international team of researchers has discovered a new extinct shark species based on the findings of 20-million-year-old fossilised teeth, that measured up to 4.5 centimeters tall. The newly discovered species has been named 'Megalolamna paradoxodon' and is believed to be ancestors of the great white sharks. Scientists have estimated the shark to be roughly four metres long.
