So, those wibbly little arms do serve a purpose, after all...
This was a "glorified sketch" I'd prepared with John Conway for his "All Yesterdays" presentation, about new insights on how dinosaurs might have looked. Too bad my real-life affairs kept me from participating further into this project.
Here, I'm speculating on possible wattles, scales and fleshy bits that might adorn the face of Majungasaurus, a majorly weird abelisaur. Majungasaurus also possessed a bony dome on top of its skull, here I imagined this structure as the base of a big, keratinous helmet-horn.
Another speculation I entertained was the possible use of abelisaurs' tiny arms for intra-spesific displays.
