Triassic Tooth from Redonda Formation, labelled as possibly Postosuchus

[DarasFossils]

Hello, I bought this tooth from a popular fossil selling website where it was labelled as 'Postosuchus?' but the description says it is from the Redonda Formation which has not had a Postosuchus formally described from it. I'm aware there a few other species from this formation that are also pseudosuchians and could have a similar type of tooth, which I do not mind if it is one of them. Although, I absolutely love Postosuchus as a creature and I hoping that is what it is, though I know it's definitely unlikely. From my research, I assume it's Redondasaurus but this particular site has several other teeth from this formation specifically labelled as Redondasaurus so I assume there is a reason why they labelled this one and a few others differently. I've seen small teeth like this labelled as Coelophysis but I know that's extremely unlikely because it's not recurved but if it was that would be super cool! I don't have the greatest lighting equipment in my house to take pictures of it, but I can provide some shotty ones if that would be helpful! The tooth is 0.74 inches long, so quite small. The picture below is from the website I bought it from and it shows the detail much better than a photo I could take. Please don't be afraid to disappoint me! I just want to know what this tooth is!

It looks like an Archosauriform tooth that's all I can say.  These isolated teeth are hard to ID and best looked at by paleontologists who are familiar with these deposits.
