Taxonomy

The name derives from "Latin pulmonis, a lung, and Greek skorpios, a scorpion"[2]

Its fossils were found in the East Kirkton Limestone at East Kirkton Quarry, West Lothian in Scotland. The diet of Pulmonoscorpius is not known directly, but it is probably that it preyed on smaller arthropods, and small tetrapods.[3] Most complete specimens were 13 to 280 mm in length. A large, fragmentary specimen was estimated to be 700 mm (0.7 metres) long when complete. The only portions preserved were the outer portions of the cuticle, which were estimated to only be 15-18 μm thick in the largest specimen.[2]

gollark: It's equivalent to *10* rot13 transformations, so it's extremely security.
gollark: Yep!
gollark: Luca_S: PotatOS also has a 5rot26 encryption engine built in.
gollark: PotatOS also includes Lolcrypt™ technologies.
gollark: Cool potatOS feature: it has more fun termination messages.
