My rarest echinoid fossil to date! It’s a cidarid from the lower Glen rose formation, found North of San Antonio, TX. I don’t have a positive ID just yet, but I’m aware of someone finding a Paracidaris texanus at the same site. To put it’s scarcity into perspective, this is the first one I’ve ever seen and I’ve been fossil hunting in this formation for years. It may be several more years before I find another. #echinoidea #cidaroida #fossil #fossilcollecting #fossilhunting #paleontology #fossicking #nature #geology #outdoors #hiking #seaurchin #limestone #sanantonio #texas #hillcountry #cretaceous #extinct #marine #animal https://www.instagram.com/p/BumKRJJgH98/?utm_source=ig_tumblr_share&igshid=1kvakv8cxgft4 -- source link
