1100-million-year-old spider attack fossil
The extraordinarily rare fossils are in a piece of amber that preserved this event in remarkable detail. This spider lived in the Hukawng Valley of Myanmar in the Early Cretaceous – between 97-110 million years ago – almost certainly with dinosaurs wandering nearby.
266 pound Rhino skull
Just 2 percent of fossils are found in volcanic rock, because the heat usually incinerates organic matter. It's even rarer to find a mammal fossil.
The skull and jaw of the rhino found in Cappadocia, central Turkey, weigh 66 pounds (30 kilograms). They are thought to have belonged to a large two-horned rhino, Ceratotherium neumayri, a species common in the Eastern Mediterranean Province during the late Miocene.
3Largest prehistoric Megalodon shark jaw ever assembled
The late Mr. Bertucci found fragments of the ferocious species in the rivers of South Carolina. The jaw set is composed of 182 fossil teeth, some over seven inches long.
4Gigantic ant fossil
They describe a new fossil species of giant ant, which they've named Titanomyrma lubei. This winged queen ant lived in the Eocene Epoch about 50 million years old. It had a body just over five centimetres long — comparable to a hummingbird — a size only rivaled today by the monstrously large queens of an ant species in tropical Africa.
5Peru's giant penguin
Part of a now-extinct diversification of giant penguins, Inkayacu certainly would have stood out when compared to its living relatives. At an estimated mass of 54-59 kilograms, Inkayacu was roughly twice as heavy as today's emperor penguin, and, like its giant cousin Icadyptes, it had a hyper-elongated bill which it used to snap up fish in the ancient equatorial sea.
Scientists also found the animal's skull. That's highly unusual but fortunate because it gave them the ability to work out the biology of the animal.
The little creature was probably less than 6 inches (15 cm.) long and shared similar characteristics with the saber-toothed squirrel in the Ice Age movies. But Cronopio likely ate insects, not the nuts that drive the animated character Scrat so crazy, and was a dryolestoid, an extinct group more like today's marsupials than squirrels, scientists say.
7Extinct whale fossil found on Santa Cruz Beach
Director Gary Griggs from the Institute of Marine Sciences at the University of California said that the fossils in the photo were most likely from an extinct Pliocene-era whale.
8Nest of 15 baby dinosaurs found in Mongolia
The analysis of the 70-million-year-old nest by Fastovsky and his colleagues found that all 15 dinosaurs – at least 10 of which are complete specimens – were about the same size and had achieved the same state of growth and development, suggesting they represent a single clutch from a single mother. The discovery also indicates that the young dinosaurs remained in the nest through the early stages of postnatal development and were cared for by their parents.
9A perfect horsetail fossil
10Strange phallus-shaped worm fossil
The area is one of the most important fossil deposits for understanding the early evolution of life during an era of increasing biodiversity on Earth known as the Cambrian Explosion, which started about 542 million years ago.
