Researchers stumbled across a bizarre species of blind cave fish with a mysterious, horn-like structure protruding from its head and a lack of scales or pigmentation.
Science has identified some 2 million species of plants, animals and microbes on Earth, but scientists estimated there are millions more left to discover, and new species are constantly discovered and described. The most commonly discovered new species are typically insects, a type of animal with a high degree of biodiversity. Newly discovered mammal species are rare, but they do occur, typically in remote places that haven't been well studied previously. Some animals are found to be new species only when scientists peer at their genetic code, because they look outwardly similar to another species — these are called cryptic species. Some newfound species come from museum collections that haven't been previously combed through and, of course, from fossils. Read below for stories about newly discovered species, both alive on Earth today and those that once roamed the planet.
A never-before-seen species of pterosaur had hundreds of hooked teeth that helped it filter its food in a similar way to living flamingos.
A previously unknown extinct tortoise was revealed in an investigation on these giants' evolutionary history.
A 120 million-year-old bird fossil from China has some rather unusual dinosaur-like features in its otherwise standard avian skeleton, including a weirdly T. rex-like skull.
Researchers have isolated viable microbes from melting permafrost after tens of thousands of years. But don't worry; they infect only amoebas.
Scientists recently discovered the first non-avian theropod dinosaur with a streamlined body similar to that of penguins, auks and other modern diving birds.
The new "dwarf dinosaur" species lends more evidence to the "island rule," which posits that animals evolving on islands become smaller than their mainland counterparts.
Paleontologists have discovered fossils belonging to a newfound species of tyrannosaur, which could fill an important gap in the evolutionary history of T. rex.
Paleontologists in China have examined the remarkable gut remnants of a birdlike dinosaur that lived more than 100 million years ago.
Researchers in Wyoming have named a new species of plesiosaur defined by its long neck and snappy jaws.
Meet Mbiresaurus raathi, the oldest African dinosaur (and one of the world's earliest) whose neighbors lived in Brazil.
Scientists have identified a woodlouse relative — a 10-inch-long, creamy yellow critter called Bathynomus yucatanensis from deep in the Gulf of Mexico.
Researchers captured a rare flower-like sea pen on video in the deep sea and believe it could be a new species.
A newly described Cretaceous dinosaur had puny arms like Tyrannosaurus rex, though the two species were not closely related.
An herbivorous dinosaur used its vicious-looking claws to forage for plants near the shores of Cretaceous seas.
A new species of glass frog has been named by a cryptocurrency organization, triggering concern over the high environmental cost of crypto.
Scientists recently described six new species of miniature frogs that inhabit forest floors in Mexico and Guatemala.
Scientists discovered the fossil tooth, ribs and vertebrae of three gargantuan ichthyosaurs, which may have been some of the largest animals ever to live.
A newfound millipede species from the Appalachian Mountains was named after the famous singer by the scientist who described the arthropod (and is a devoted Swift fan).
