Prehistoric remnant

I always remember being taught at school that ferns were the last reminder from the prehistoric era. 

Ferns first appear in the fossil record about 360 million years ago in the late Devonian period, but many of the current families and species did not appear until roughly 145 million years ago in the early Cretaceous, after flowering plants came to dominate many environments.

Anyway, it gave me a blip today, which was my first day back at work.

I hope you have had a good midweek.
