A Peek Into The Past: Massospondylus Embryos!
This is a 190 million year old Massospondylus embryo found in South Africa. Due to their delicate nature, embryos do not generally fossilize. This fossil, along with the rest of its clutch (see above), are 1 of only 3 examples of dinosaur embryos currently known to science.
This fossil represents what is believed to be a soon to hatch Massospondylus. The neck, legs and head size, point to the dramatic change they under go during life. For example, as babies, these dinosaurs would walk on all fours, while as adults they walk primarily on their hind legs (check out the Julius Csotonyi image above). The lack of developed teeth also seem to indicate that hatchlings would be dependent on their mother for food and safety for the beginning stages of life.
The ROM’s palaeontology department played a major role in studying these fossils and are currently on special display at the Museum.
