The nesting site of medium sized dinosaurs of the early Jurassic period which shows footprints and fossil embryos dating back to 190 million years have been uncovered in the Golden Gate Highlands National Park in South Africa.
These species known as the Massopondylus usually grew to be 4 to 6 meters long when adults but their eggs were hardly six centimeters in diameter.
Based on available evidence, researchers of Canada and South Africa have concluded that the hatchlings remained in the nests till they grew to double the size. Also, the young of the species walked on four legs in their formative years but began to walk upright on two legs when became adults.
The team has discovered as many as 10 nests at various levels of the rocks and there were nearly 34 eggs in each close-knit group.
