Кызыктуу фактылар
Massospondylus was one of the first dinosaurs to be named, described by Richard Owen in 1854.1
Its name means 'longer vertebra' because Owen thought the neck bones were tail bones.1
Fossil eggs and embryos of Massospondylus have been found, and they are among the oldest known dinosaur eggs.1
The eggshell of Massospondylus was extremely thin, less than 0.1 mm (0.0039 in) thick.1
Baby Massospondylus had proportionally longer arms and a larger head than adults, suggesting they may have walked on four legs when young.1
Massospondylus could speed up or slow down its growth depending on how much food was available.1
The oldest known Massospondylus was about 20 years old when it died.1

Эң көп берилген суроолор: Massospondylus
?How big was Massospondylus?
Massospondylus was about 4 to 6 metres (13 to 20 feet) long, with a small head, long neck and tail, and a slender body. It weighed around 150 kilograms (330 pounds) according to the Natural History Museum.13
?What did Massospondylus eat?
It was probably a herbivore (plant-eater), though some scientists think it may have been omnivorous. It used its sharp thumb claws to pull down branches or dig up plants, and it may have swallowed stones to help grind tough leaves in its stomach.12
?Did Massospondylus walk on two legs or four?
It is now considered to have been bipedal (walked on two legs), though it was long thought to be quadrupedal. Some studies suggest babies may have walked on four legs, but newer research says it was bipedal at all ages.1
?When did Massospondylus live?
It lived during the Early Jurassic, about 201 to 184 million years ago.13
?Where was Massospondylus found?
Fossils have been found in southern Africa, including South Africa, Lesotho, and Zimbabwe, and also in Namibia. Some fossils from the US and Argentina were once assigned to it but are now considered different dinosaurs.12
?Did Massospondylus lay eggs?
Yes, it laid eggs, and some of the oldest known dinosaur eggs and embryos belong to this genus. The eggshells were extremely thin, less than 0.1 mm (0.004 in) thick.1
Мифти талкалоочу
Миф: Massospondylus was a four-legged (quadrupedal) dinosaur.
Чындык: Scientists now think Massospondylus walked on two legs (bipedal), though babies may have been four-legged.1

- The first fossils of Massospondylus were found in 1853 or 1854 by Joseph Millard Orpen and his brothers on a farm in the Drakensberg mountains near Harrismith, South Africa. Their father donated the fossils to the Hunterian Museum in London, where Richard Owen described and named the dinosaur in 1854.1
