Here are a couple of small rattlesnake fangs that split open showing their hollow structure – venom flow through the fangs up to tip where there’s a small opening. Rattlesnakes tend to shed their fangs every 6 – 10 weeks. Found in Nebraska on a Harvester Ant Mound. #RattleSnake

I just had a fossil echinoid named after me (Eupatagus dumonti n. sp.) and I would like to thank the authors (A.S. Osborn, R.W. Portell, R. Mooi) and The Florida Museum of Natural History (#FLMNH) for this honor. Photos of two echinoids I have donated to FLMNH. #FloridaFossils
