Serina: The Skulossi (Patreon)

And now, after posting all of them individually, here's every 290 MYH skulossus species (so far) posted together in one image for scale (along with the brontocorn, since, as previously mentioned, it was originally meant to live at the same time). They're seen from profile here so it's not evident, but they are rather wide (compared to the comparatively more slender gantuans).

These animals are like one-third macronarian, one-third ankylosaur, and one-third iguanodont, although the ratio is unequal throughout the different species.
