This recently-discovered dinosaur weighed 26,000 pounds when it stomped around South Africa's Free State Province 200 million years ago. The University of the Witwatersrand researchers who found the animal's fossils dubbed it Ledumahadi mafube which in the South African language of Sesotho means "a giant thunderclap at dawn." Like the brontosaurus, it walked on four legs and ate plants. From CNN:
Apart from its massive size, there are other evolutionary details about the new species that make it entirely unique, according to a new study published Thursday in the journal Current Biology.
"It shows us that even as far back as 200 million years ago, these animals had already become the largest vertebrates to ever walk the Earth," Choiniere said.
The researchers believe that Ledumahadi was a transitional dinosaur, an evolutionary experiment itself during the Early Jurassic period. The forelimbs of this dinosaur are more "crouched," while being very thick to support its giant body.
