Riguetti et al, 2022. Figure 4 - known elements of Jakapil in white show it is known almost entirely from a lower jaw, a scapula, a few vertebrae, osteoderms, and various fragments of rib/leg/hip/upper-jaw/vertebrae/etc.
Happy #FossilFriday from the enigma that is #Jakapil. It seems to be a ~1 meter long remnant of a very early branch of the armoured dinosaur lineage (containing stegosaurs and ankylosaurs), but many of its features are more similar to other herbivorous dino families.
What on Earth was this thing?
