Nichollssaura was a small, fast-swimming marine reptile that lived in the sea that once covered Alberta, Canada. It was a plesiosaur, not a dinosaur, and had a long neck and four flippers for paddling through the water. This creature helps scientists fill in a big 40-million-year gap in the plesiosaur fossil record of North America.1

1

The fossil was discovered accidentally by giant electric shovel operators in an oilsand mine. The shovel cut off some bones, but the rest of the skeleton was almost complete.1

2

This plesiosaur was named after Dr. Betsy Nicholls, a famous paleontologist. The first name Nichollsia was already used for a type of isopod, so scientists changed it to Nichollssaura.1

3

Nichollssaura had 165 gastroliths (stomach stones) inside it. The stones were smooth and round, probably swallowed to help grind food.1

4

The stomach stones came from rocks that were 8 to 10 million years older than the plesiosaur itself. This suggests Nichollssaura may have swum west to collect pebbles from ancient beaches.1

5

It lived about 110 million years ago in the Boreal Sea, a warm shallow sea that covered parts of North America.1

6

The holotype specimen is on display at the Royal Tyrrell Museum in Alberta, Canada.1

The specimen was found in 1994 by shovel operators Greg Fisher and Lorne Cundal at a Syncrude oilsand mine in Alberta. It was named Nichollsia borealis by Druckenmiller and Russell in 2008, but the name was changed to Nichollssaura in 2009 because Nichollsia was already taken.12
