Tidgy's Dad Posted January 4 Share Posted January 4 (edited) Love this. Though I wish we could have had a photo or even a diagram. And "However, Timorebestia is a distant, but close, relative of living arrow worms, or chaetognaths." Distant, but close? Edited January 5 by Tidgy's Dad 1 Life's Good! Tortoise Friend.

Doctor Mud Posted January 5 Share Posted January 5 Very interesting! Thanks for sharing. I particularly like the diagram comparing Cambrian food chain to recent. Amazing that chordates were at the bottom of the food chain back then! 1 Link to comment Share on other sites More sharing options...
