Washington, December 14 (ANI): Scientists have discovered the fossil of a new species of extinct pygmy sea cow, which is one of the first fossil mammal species found in Madagascar from the mysterious time period between 80 million years ago and 90,000 years ago.
Sea cows, or sirenians, today include manatees and dugongs.
"There's a big gap where we really don't know anything about what's going on in the fossil record," study leader Karen Samonds, of McGill University in Montreal, Canada, told National Geographic News.
Known from a roughly 40-million-year-old skull and a few ribs, the new species has been named Eotheroides lambondrano, after the Malagasy word for dugong, which translates to "water bushpig."
At about seven feet (two meters) long, the ancient pygmy sea cow was smaller than the modern dugong, which ranges from about 8 to 10 feet (2.4 to 3 meters) in length.
The pygmy sea cow would have been "a neat in-between" animal in the evolution from primitive land-dwelling mammals to today's aquatic sea cows, according to Samonds.
E. lambondrano is also unique in that its closest relatives would have lived in what is now India and Egypt, according to the study, making its Madagascan location all the more special.
"This fossil gives us a new glimpse not just at a new time period, but at a new place," said Samonds.
"Madagascar already has a lot of strange beasts, and we now have a glimpse of this species from so far away," she added. (ANI)
