Oldest brain in a backboned animal found in fish fossil

Posted by in categories: biotech/medical, neuroscience

Very old brain, some ancient philosophy maybe…

A fossilised fish originally dug up more than a century ago in an English coal mine has been shown to hold the world’s oldest brain in a vertebrate animal.

CT scans revealed the new internal features including a brain and cranial nerves about 2 centimetres long.

Soft tissue such as internal organs decay very quickly and very rarely fossilise.
