I found a Neospirifer Rocky Montanus brachiopod completely intact from a gravel pit here in Fairborn, Ohio. The clam was shut, and you could see mud jammed along the crack. Perfectly consistent with sudden death by mud. Based upon my estimate from holding the specimen in my hand, it was more like 3000 years old, not the 300 million you find in the literature. But what do I know against the mythology preached by the Darwinians?
