When the carcasses of nine blue whales were spotted in sea ice off the coast of Newfoundland in April, it was an environmental tragedy. Blue whales are endangered all over the world, and only about 240 now live in the western Atlantic Ocean near Canada.

New Species Of Dinosaur Found In Alberta
A dome-headed dinosaur skull found in southern Alberta is helping scientists rethink some of their ideas about dinosaurs.
The skull was found in 2008 by a team of scientists led by Dr. David Evans of the Royal Ontario Museum.
The skull is about 85 million years old.
The top of the skull is made of a dome-shaped mass of solid bone about 10 centimetres thick.
This means the dinosaur belonged to a group of dinosaurs called pachycephalosaurs (“thick-headed lizards”).
The scientists compared the skull to all of the known pachycephalosaur specimens in the world – about 600 of them.
They learned that there are 16 different species within that group, and the skull discovered in Alberta belongs to a species that has never been seen before.
