Scolosaurus cutleri

One of the greatest mysteries in the history of Cretaceous dinosaur excavation is how William Edmund Cutler managed to find and extract an extraordinary ankylosaur that Franz Baron Nopcsa later named Scolosaurus cutleri in his honour, and how he escaped without losing his life. Apparently, Cutler just happened to be strolling past an almost impossible to reach location halfway up a cliff when he stumbled upon Scolosaurus sticking feet first out of the rock. As he chiselled away the cliff face, the specimen crashed down on top of him, and he suffered serious upper body injuries. Death was avoided, but he was none the wiser for it, and continued to ignore all sensible health and safety precautions right up until he fell to malaria in Tanzania whilst working for the British Museum of Natural History in 1925.

In 1971, Walter Coombes was convinced that only a single Campanian-aged Late Cretaceous ankylosaurid was present in North America and sunk Scolosaurus into Euoplocephalus tutus along with Anodontosaurus lambei and Dyoplosaurus acutosquameus. And that was accepted for many years. However, following the lead of Victoria Arbour who reinstated Dyoplosaurus as a valid standalone critter in 2010 and suggested Anodontosaurus should be reinstated too, Paul Penkalski and William T. Blows officially rescued Scolosaurus from the pit in 2013 when they found it to be distinct from Euoplocephalus in the structure of its forelimb and form and details of its armour, and from Dyoplosaurus in features of its armour and design of its pelvis.
Discovery
The first fossils of Scolosaurus were discovered in Quarry 80 at Deadlodge Canyon, Dinosaur Park Formation, Alberta, Canada, in 1914 by William Edmund Cutler.
The holotype (NHMUK R.5161) is a vertebral column, forelimb, hindlimb, and armor.
