Extreme armour in the world's oldest ankylosaur Supplementary Material
Overview
Paper Summary
This supplementary material provides a detailed anatomical description of new fossil material attributed to the early ankylosaur *Spicomellus afer* from the Middle Jurassic of Morocco. The fossil material includes a partial skeleton with unique "T"-shaped dorsal ribs bearing co-ossified dermal spikes, an elaborate cervical half-ring, and other armor elements. Phylogenetic analyses place *Spicomellus* as an early-diverging ankylosaur, suggesting early development of dermal armor.
Explain Like I'm Five
A new fossil of an armored dinosaur, *Spicomellus*, was found in Morocco. Its unique spikes and armor show how these dinosaurs evolved defenses early on.

Rating Explanation
This paper describes important new fossil material of an early ankylosaur, *Spicomellus afer*, providing insights into the evolution of armor in this group. While limitations exist due to the incomplete and disarticulated nature of the material, the fossil's unique features and phylogenetic placement make it a significant contribution to our understanding of early ankylosaurs.
