Neostreptognathodus is an extinct genus of conodonts from the Cisuralian (Early Permian).

Use in stratigraphy

The top of the Artinskian (the base of the Kungurian) stage is defined as the place in the stratigraphic record where fossils of conodont species Neostreptognathodus pnevi and Neostreptognathodus exculptus first appear.

Neostreptognathodus costatus is from the Early Permian Amushan Formation in Xiwuzhumuqin Qi, Inner Mongolia, in China.

gollark: Well, we could engineer humans with better DNA error correction or something, eventually.

gollark: Forever might be an overestimate, but cancer generally will probably stick around for a while as it is a complex and hard-to-cure thing.

gollark: ... maybe these are just hard problems which they're working on, rather than some kind of conspiracy?

gollark: It seems like the problem here might be lack of systems to track and respond to demand, since I think lots of people probably would be willing to pay some money for a ventilator to be available if they need it during this pandemic.

gollark: Ones higher than LEO will stick around for a while. They won't *work* for a hundred years though.
