Poromitra oscitans Poromitra oscitans summary page WoRMS - World Register of Marine Species - Poromitra oscitans Ebeling, 1975
Mountain chicken and Sulawesi snouter. As extinct species go, I've heard "Demon duck of doom" and "Platyzilla"
The dinosaur Megapnosaurus. There are two reasons I like this dinosaur so much. 1. A paleontologist discoveries it and named it Syntarsus, years later a couple of entomologists realized that Syntarsus the name of a beetle. They renamed it to Megapnosaurus without asking the discoverer of the dinosaur. The reason they did not ask him was because they thought he was dead. 2. Megapnosaurus means “Big Dead Lizard”
Fairly certain he means the Slippery Dick that was already mentioned on this thread, (Assuming that's what you are confused about??)
There Is Also The Satanic Nightjar (Eurostopodus diabolicus) Which Apparently Sounds Like It Is Plucking Someone’s Eye Out.
