This is the locality in the Campbellton Formation where we’ve collected the almost complete shark Doliodus problematicus. It’s a really interesting specimen, it’s the first specimen in the world that shows that sharks had pectoral fin spines, the preservation is excellent, all the teeth are there in the jaw, as well as the braincase is well preserved. It’s also the place where we have found sea scorpions, these are giant lobster-like animals that grew up to, at least at this locality, a metre to almost two metres in length, and the shark and the sea scorpions, or these eurypterids as they are known, were living in the same environment.
