It’s a common view that opposable thumbs are a key feature that distinguishes us from most other species, but a flying reptile that clambered through the trees 160 million years ago isn’t one of them, according to analysis of a newly discovered species… Continue reading Ancient “Monkeydactyl” bears the oldest known opposed thumbs
While we’ve seen fossilized dinosaur eggs and embryos before, paleontologists have now discovered an unprecedented three-for-one – a fossilized dinosaur parent sitting on a nest of eggs, in which embryos are present.Continue ReadingCategory: Biology, S… Continue reading Fossilized dinosaur found sitting on eggs – with embryos inside
Researchers have identified the oldest known fossils of primates, dating them to around 65.9 million years ago. That’s just after one of Earth’s biggest mass extinction events, and it suggests that the ancestor of all primates originally lived alongsid… Continue reading Oldest primate fossils indicate our ancestors walked with dinosaurs
A new study has analyzed asteroid dust recently discovered in the Chicxulub asteroid crater. The findings further support the theory that the dramatic impact was the cause of the mass extinction event that wiped out the dinosaurs.Continue ReadingCatego… Continue reading Iridium levels of submerged crater support dinosaur extinction theory
A new study published in the journal Nature is describing the extraction and sequencing of the oldest known sample of DNA. The sample comes from an ancient species of mammoth found in the Siberian permafrost and dates back nearly 1.2 million years.

A new study is questioning the origin of the body that smashed into Earth’s surface millions of years ago, causing a global extinction event that wiped out the dinosaurs. According to the research, the impactor may have originated from a massive sphere… Continue reading Dinosaur extinction may have resulted from death of “sungrazing” comet
Just last year, scientists declared that Spinosaurus was the first dinosaur known to swim through the water, preying upon fish as it did so. A new study, however, suggests that it was probably more of a shore-based feeder.Continue ReadingCategory: Biol… Continue reading Aquatic dinosaur may have been a shoreline stalker, not a fish-chaser
Probably the world’s most famous family of dinosaurs, the tyrannosaurs included the 40-ft (12-m) Tyrannosaurus rex within their ranks. Newly studied fossils now suggest that the reptiles were about “the size of a border collie” when first hatching from… Continue reading Fossil analysis suggests newly hatched tyrannosaurs were dog-sized
Tyrannosaurus rex may have ruled the land in the time of the dinosaurs, but the mosasaur was likely the most ferocious reptile in the sea. A new species of the creature was recently classified, which distinguished itself with teeth like those of a shar… Continue reading Porpoise-sized mosasaur sported specialized shark-like teeth
