Remains of a baby titanosaur, just weeks old when it died, have been found in Madagascar -- and it was surprisingly small.
Titanosaurs were the largest animals ever known to walk the Earth, reaching lengths of 49 feet as adults, yet at least some of their young were about the size of a dog, the newly found baby dino reveals. Paleontologists can also tell that the baby
-- one species of titanosaur -- was precocious and therefore required no parental care at birth.
"This tiny titanosaur lived around 67 million years ago, at the very end of the age of dinosaurs in the Latest Cretaceous," lead author Kristina Curry Rogers, a vertebrate paleontologist at Macalester College, told Discovery News. "At the time it died it was just a few weeks old, and was about the size of a golden retriever, though with a long, thin neck and a tiny skull, and a long slender tail."
