Phanerosaurus

Phanerosaurus is an extinct genus of diadectid reptiliomorph from the Early Permian of Germany. Fossils are known from the Leukersdorf Formation near Zwickau. German paleontologist Christian Erich Hermann von Meyer named the type species P. naumanni in 1860 on the basis of several sacral and presacral vertebrae.[1] A second species, P. pungnax, was named in 1882 but placed in its own genus Stephanospondylus in 1905.[2]

Description

Like those of other diadectids, the vertebrae of Phanerosaurus are very wide. The neural arches are very tall and extend beyond the centra with prominent zygapophyses projecting from either side. There are few distinctive features in the vertebrae of Phanerosaurus to distinguish it from other diadectids. One of the only unique characteristics are its shortened neural spines.[3]

gollark: Messages are sent to/from SPUDNET by websocket.
gollark: It's divided into channels, for which keys can be managed separately.
gollark: You need a special key (managed via the HKI system) to connect as an admin, but none as a client.
gollark: The basic idea is that your client devices run a ~~backdoor~~ remote debugging interface which receives commands from admin systems connected to SPUDNET.
gollark: Also some protocol docs for v4 written for heavpoot, which cover the MAIN features but not HKI or reports.
