Heading to my bed but thought i'd have some fun beforehand. So, you get a double one today...FUNSIES! Plus this is going to be a properly short one. So, what is Snarl, the guy who may not be in the movie. Snarl is interesting because he's by far the most conservative of the dinobots. He lacks many of the exaggerated features of the others, so it makes my job easier. Despite several people's arguments of ankylosaur features, Snarl is almost indistinguishable from the Stegosauridae. The elongate and thin head, the relatively thin body, the sagittal plates and the tail spikes (thagomizers), classic stegosaurid. The lack of strongly spike-like plates or well developed shoulder spikes exclude all but perhaps...four taxa, all of which are in the Stegosaurinae. (god bless wiki_ Miragaia is distinguished from Snarl due to its quite thin plates and its hyper-elongate neck. Wuerhosaurus has quite bizarre square plates so shouldn't be included. This leaves us with Hesperosaurus And of course Stegosaurus Unfortunately...this is kinda where we hit a wall. Both of these animals have diamond plates...and given the limited information Snarl presents us, that's basically our big identifier. The arrangement of the plates varies based on reconstruction. Hell, even the number of thagomizers can vary at times. At this data scale it would be difficult to establish genus or species, whether its something new or just a variant within a taxon. This gives us our first stonewalling, and spoiler, not our last. I cannot in good conscience place Snarl in either an established taxon or a new one. I can however give him a family level identification, and I argue that Snarl is an indeterminate stegosaurine stegosaurid. Sadly, I don't think a strong enough argument can be made to get better taxonomic resolution.
