Permian reptile teeth?

[ThePhysicist]

Hi y'all, I was thinking again about some Permian reptile teeth, I've seen them referred to online as 'parareptile,' but would like collective and/or professional insight. They are pretty distinctive, with a smooth labial face, and a striated lingual face. These are all from Waurika, OK (Wellington fm, Lower Permian). I have several examples, but they're not much different from these two. @jdp @dinodigger

 

3.5 mm tall:

 

 

2 mm tall:

 

 

They vaguely remind me of a Caseid tooth, which has the same character of the striations/no striations (or I at least think this one is Caseid...).

1 and 2 are cf Seymouria. 3 could be a few things but caseid is a fair guess.

Interesting... the ornamentation seems unlike that of the teeth I've seen published, which have minor ridges at the base of the crown but terminate before the apex - the enamel is otherwise smooth. Do you think this is within the range of possibilities for intrageneric/familial variation?

Here is a tooth that I thought fit Seymouria a bit better (especially with the smooth enamel and curving mca):

 

 

Again, thank you for your help - there seems to be a dearth of information on these Permian teeth available to us amateurs. What are other possibilities for the "Caseid" that I could look into?
