Edmonton's Nodosaur

In the news lately there has been a lot of talk about a nodosaur mummy. This week, therefore, I thought it would be prudent to discuss a nodosaur, though honestly a totally different nodosaur than the fossil mummy. This week's nodosaur is known as Edmontonia and the genus contains two species: E. longiceps and E. rugosidens. Nodosaurs like Edmontonia were covered in osteoderms and armor that we will see plenty of this week. Known from materials originally discovered in 1915 from the Edmonton formation of Southwestern Alberta. Specimens have been discovered as recently as 2010 and the taxonomic history of the genus is interesting and complicated. A lot is known about Edmontonia and so we will have a lot to discuss this week, but before we do, appreciate some art based on the original finds.
