Early Eocene
Green River Formation

20mm walking stick with huge 20mm antennae on 62mm slab.

Walking sticks date back at least to the Late Jurassic.  It turns out you can evade extinction for over 150 million years just by moving slowly and looking like a stick.  Becoming large and having large teeth has a long history of making you surprisingly vulnerable.
