In 1927, the singer Mary Garden cut her hair short and wrote an article explaining why:
I consider getting rid of our long hair one of the many little shackles that women have cast aside in their passage to freedom.
This statement was one of the many reasons why women began to cut their hair short from the late 1910s and early 1920s onwards.
The dinosaurs (literally "fearfully great lizards") were giant reptiles that lived on Earth for over 100 million years from the late Triassic period (about 230 million years ago) until the end of the Cretaceous period (about 65 million years ago).
They became extinct due to some sort of catastrophic event, possibly an asteroid impact.
