A single tooth, part of a jaw, a piece of a skull: sometimes, that is all scientists have to tell the story of animals that went extinct millions of years ago. But new methods developed by scientists at the American Museum of Natural History and Stony Brook University are making it easier to accurately place these animals in the tree of life with partial fossils and DNA data.
A deep-water creature once thought to be one of the world’s largest sea anemones, with tentacles reaching more than 6.5 feet long, actually belongs to a new order of animals.
Distant exploding stars observed by NASA’s Hubble Space Telescope are providing astronomers with a powerful tool to check the "prescription" of supernovae that act as natural “cosmic lenses.” Astronomers use these lenses to capture a magnified view of the remote universe.
New study, led by scientists at the American Museum of Natural History, shows that living sharks are actually quite advanced in evolutionary terms, despite having retained their basic “sharkiness” over millions of years.
