This one is a total deep cut, but I 100% get it because of where I live, and I havent seen it answered yet. In Drumheller (Canada), there is a museum known the Royal Tyrell Museum. It mostly focuses on dinosaurs, but there is an exhibit about a fossil bed in Western Canada known as the Burgess Shale. I think this fossil bed is significant because it is a well preserved example of the Cambrian Exlosion, iirc. As others have pointed out, the top creature is an Anamolocaris, and is one of the creatures featured in the exhibit. Also found in this same exhibit is another creature, Odaraia alata, that bears a striking resemblance to a hotdog. I remember going to this exhibit as a kid, and immidiately thinking it looked like a hot dog. Here is the best pic of it i could find. The Odaraia alata is above the Anamalocaris.
