A little survivor

A LINE of mini-sharks thought to have perished in Earth’s “Great Dying” event some 250 million years ago, in fact lived another 120 million years, said researchers who found samples of their minuscule fossil teeth.

The strange creature, which measured no more than 30cm in length and likely sported a hook-like protrusion in place of a dorsal fin, may have survived the calamity by hiding away in the deep seas, the research team wrote in the journal Nature Communications.
