They are natural history’s superstars, yet we know surprisingly little about the diversity of dinosaurs. Now a mathematical model provides an estimate of how many different genera of dinosaurs there were.
Australian scientists have discovered that the platypus is significantly older than previously thought: it may have been around since 120 million years ago, meaning it lived alongside the dinosaurs.
Climate modelers already had their hands full explaining what warmth-loving crocodiles were doing in the high Arctic 90 million years ago in the Cretaceous period.
An English Grad Student has confirmed that fossils discovered a decade ago belong to a brand-new species of Carcharodontosaurus, a Mesozoic predator even larger than T rex. The fossils were from Niger.
Spanish scientists have unearthed what could be Europe's largest dinosaur boneyard, finding the remains of 65ft plant-eaters never before discovered on the continent. The palaeontologists believe they have found eight different species amid the 8,000 fossils discovered so far.
Scientists have found in southern Utah a nicely preserved skull with jaws containing 800 teeth, scaly skin impressions and other fossil remains of a new species of duck-billed dinosaur from 75 million years ago.
Scott Sampson, the curator of the Utah Museum of Natural History said in other reports that it resemble Arnold Schwarzenegger, in that "It's all pumped up". A massive fossil skull found in southern Utah represents a new species of duck-billed dinosaur, researchers say.
From The Hankyoreh (Korea): An international team supported by the Gyeonggi provincial government has excavated a rare dinosaur fossil in the Gobi Desert in Mongolia.Hwaseong City in Gyeonggi Province and an international dinosaur excavation team led by Lee Yung-nam, a researcher …
The dinosaurs, along with the majority of all other animal species on Earth, went extinct approximately 65 million years ago.
"Growing evidence shows that the dinosaurs and their contemporaries were not wiped out by the famed Chicxulub meteor impact alone, according to a paleontologist who says multiple meteor impacts, massive volcanism in India and climate changes culminated in the end of the Cretaceou …
This article in Biology Letters looks at the patterns of diversification and timing of evolution within Neoaves (which includes almost 95% of all bird species).
From the article: The amber, found in Spain, preserved 26 strands of silk; many of them connected to one another. Glue droplets are visible on the web and prey includes a fly, a mite, a beetle and a wasp.
Original article Widespread nowadays in freshwater and coastal seas of the cold and temporal zones, lampreys are a jawless vertebrate group that has been in existence for more than 300 million years but left a meagre fossil record.
Testing models of macroevolution, and especially the sufficiency of microevolutionary processes, requires good collaboration between molecular biologists and paleontologists.
Another amazing dicsovery in China. A bird fossil that's pushing the date of the famous speciation event of flying birds.
