Hey everyone, these are not my photos but ones from a listing on a popular auction site. There isn’t any info given about the fish, other than that they are a pair and weigh 35g.
They look to be from the Green River Formation, but I’m not an expert so if you have a different idea, I’m all ears. My main question, however, is if anyone can identify the species? Judging by the coin size, I’m estimating that the size of the slab is about 4cm high and 6-7cm long. Any ideas would be appreciated, thanks!
