By Amina Khan Nov 30, 5: A study of these remains helped scientists learn how these flying reptiles developed and whether they were involved parents. The find, described in the journal Science, offers an unprecedented look at the early development of these ancient flying reptiles. They lived from the late Triassic to the end of the Cretaceous roughly million to 66 million years ago. Scientists have discovered a number of fossil dinosaur eggs, and found that the large marine reptiles called ichthyosaurs actually gave birth to live young. But the biology and development of pterosaurs, even with the discovery of a handful of non-flattened eggs in recent years, has remained something of an enigma. A visualization of the bones inside a pterosaur egg. But a mother lode of hundreds of eggs and bones discovered in a sandstone block in northwestern China may finally paint a fuller picture of these animals at the earliest stage of their lives. All the specimens seem to be roughly million years old, dating back to the Early Cretaceous period , and appear to belong to the same species: The researchers counted eggs but there may be up to , given how the eggs are piled on top of each other.

Share this article Share The sluggish progress of the reptiles has helped scientists build up a genetic picture of the archosaurs that predated dinosaurs, pterosaurs, birds and crocodilians. The study, published in the journal Science, suggests that the ancestor of all archosaurs had an extremely slow rate of molecular evolution, which sped up in the bird lineage. After the meteor strike, which is thought to have wiped out the dinosaurs 66 million years ago, surviving birds experienced a rapid burst of evolution.

This led to nearly all the species of birds seen on Earth today including Snow geese pictured , of which there are more than 10, This led to nearly all the species of birds seen on Earth today, of which there are more than 10, In related studies, also reported in Science, researchers compared the genomes of 48 bird species selected from all major avian groups, including the woodpecker, owl, penguin, hummingbird and flamingo.

They discovered that birdsong evolved independently at least twice. Birds were also found to have lost their teeth around million years ago, when the dinosaurs still ruled. This is according to a study published last year that showed, for the first time, how the reptiles evolved in a dinosaur dominated world. Today, most modern crocodiles live in freshwater habitats and feed on mammals and fish, but their ancestors ran around on land like dogs while others adapted to life in the open ocean, imitating the behaviour of whales.

Carbon , Radiometric Dating and Index Fossils Carbon dating is used to determine the age of biological artifacts up to 50, years old. This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old. This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.

Carbon dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharaohs among other things. Carbon is a radioactive isotope of carbon. The half-life of carbon is approximately 5, years.
