Precipitation more than temperature influenced the distribution of herbivorous dinosaurs in what is now Alaska, according to new research published this month. The finding, published April 2 in the journal Geosciences, discusses the distribution of hadrosaurids and ceratopsids — the megaherbivores of the Late Cretaceous Period, 100.5 million to 66 million years ago. The work […]
The bizarre features of this mammal have scientists perplexed as to how it could have evolved; “it bends and even breaks a lot of rules” New research published today in the Journal of Vertebrate Paleontology describes a bizarre 66 million-year-old mammal that provides profound new insights into the evolutionary history of mammals from the southern supercontinent Gondwana […]
New study suggests a miniaturized origin for some of the largest animals ever to live on Earth Dinosaurs and flying pterosaurs may be known for their remarkable size, but a newly described species from Madagascar that lived around 237 million years ago suggests that they originated from extremely small ancestors. The fossil reptile, named […]
When the asteroid that wiped out the dinosaurs slammed into the planet 66 million years ago, the impact set wildfires, triggered tsunamis and blasted so much sulfur into the atmosphere that it blocked the sun, which caused the global cooling that ultimately doomed our giant predecessors. That’s the scenario scientists have hypothesized. Now, a new […]
