ESCONI General Meeting 8:00 p.m. College of Dupage, - Tech Ed (TEC) Building, Room 1038B (Map) Speaker: Lindsey Koper. Instructor, Northern Illinois University. Topic: The Rancho La Brean Dire Wolf And What Its Bones Can Tell Us: A Brief Look Into The Life Of Canis dirus And What Became Of This Great Predator-
Canis dirus, the dire wolf from the tar pits of Rancho La Brea was the dominant canid predator during the Pleistocene and thrived alongside other large carnivores such as Smilodon fatalis and Panthera atrox, the American lion. The dire wolf also interacted and coexisted with the modern wolf (Canis lupus) when it reached North America.
Looking at the fossils of Canis dirus found at Rancho La Brea both the dire wolf and modern wolf appear to be anatomically similar as well as share comparable hunting styles. At the end of the last glacial maximum Canis dirus died out along with the other megafauna of the time while Canis lupus survives into today. Clues as to why the dire wolf may have died out can be seen in the dentition and skeletal remains of this large canid.
