This week’s Fossil Friday is a Late Cretaceous sea star from Alberta (APS 1987.038). It was found in the Cardium Formation, which formed along the shallow margin of the Western Interior Seaway. This seaway bisected North America, connecting the Arctic Ocean to the Gulf of Mexico. This sea star would have lived in the warm, shallow waters along that margin.

It was found by Harvey Negrich and Don Sabo. Photo credit Howard Allen.

This was the main presentation at our May 8 monthly meeting. These meetings are free and open to the public!

Canada is blessed with many fossil reefs. Most are not easily accessible but a fair number are close enough to roads to be easily walked to or viewed. Surpri...

This week’s Fossil Friday is a tooth of Sandalodus, a Carboniferous shark. This animal was swimming in the tropical seas that covered Alberta roughly 350 million years ago. At that time, much of Alberta lay under a warm, shallow sea - more like the Bahamas today than the prairies we know now!

This specimen was found near Bragg Creek in southern Alberta. It is APS 1985.020 and was collected by Geoffrey Barrett.

Another video from Paleo 2026 has been posted! Dr. Jon Noad explains different often-overlooked trace fossils and uses comparison with living traces to show how these fossils are more numerous than we think - we just need to know what to look for.

Trace fossils provide a valuable tool in the interpretation of depositional settings. They can also be used to show the presence of ancient creatures that ot...

This week’s Fossil Friday is a Saurornitholestes tooth from the Dinosaur Park Formation. Saurornitholestes was a small theropod, closely related to Velociraptor, that would have stood about 60 cm tall and measured roughly 1.5 m long in life.

The serrations on this tooth helped it cut more efficiently into the flesh of its prey. This specimen, APS 1986.003, was found west of Iddesleigh by Donald Sabo.
