New fossil evidence, published by Oxford University in Current Biology, demonstrates the surprising speed with which mammals evolved during the ancient Jurassic period.
There is actually no uncontroversial explanation for the as-of-yet unparalleled size of dinosaurs. If you look at the distribution of large sizes in dinosaurs, one distinction becomes clear: the only dinos that were small (less than 1m) were carnivorous theropods. Except for the 70 cm Fruitadens Haagarorum, no herbivorous ornithischians were small.
How do you mark the instant when human impacts so changed the planet that the signs will remain embedded in Earth's rock record for time immemorial? That is essentially the question that three important new scientific studies tackled this month.
How could an educated citizen of the 21st century ever reach the conclusion that a saber-toothed cat or Tyrannosaurus rex preferred eating fruit over flesh?
It's taken 64 years to for scientists to be sure, but they have finally determined that bones found on the North Slope of Alaska's Brooks Range are those of an ichthyosaur, a giant marine reptile from the time of the dinosaurs.
It was a new species of hominids, primitive humans from about 15,000 years ago, reconstructed from a heap of fragmented bones found on site, including a skull and thigh bones belonging to a subject termed LB1.

"I want to be able to spread that message to as many young women as possible. Yes, you can do this, it is not that hard and do not let somebody tell you you cannot do it."
The filmmakers have gone to great lengths to make sure the portrayal of the dinosaurs and their environments are as accurate as possible, except the part about the dinosaurs talking. They really wanted moviegoers to get an accurate experience of how it might have felt to walk with dinosaurs.
Our global presence is quite recent, and although we may look different, we are actually a genetically homogenous species compared to other great apes. This makes most of our differences superficial.
If you're interested in paleontology as a career you will need to get a college degree in a relevant field, such as biology or geology. These majors require taking all sorts of science classes and math courses, too. PLEASE PLEASE PLEASE do not let this discourage you!! So many students, especially female ones, allow themselves to be intimidated by these STEM classes but there is no need for that. Give yourself plenty of time to study tough concepts and don't be afraid to ask clarification questions or ask for help. Other courses that would be useful in paleontology include geography, computer programming, GIS, anthropology, statistics, and anatomy and physiology.
How cool are dinosaurs? Spain is one of the richest areas in the world for dinosaur remains, and has devoted many museums and theme parks to their ancient predecessors. If you and your family love dinosaurs, come to Spain for a daring adventure.
I am a 21 year-old paleontologist. I live and and work in Denali National Park and Preserve in Alaska. While what I just said may seem perfectly clear to me, I get a lot of questions about what I do. People think I run around with a bullwhip. People assume I spend my day dreaming about riding dinosaurs.
What the fossil record does is force us to contemplate our place on the planet. We are but one species of several hominids that inhabited planet earth and like our distant cousins who went extinct fairly recently, our time on planet earth is also finite.
When terms like micro and macro are used to bolster the case for creationism or a "designer," the dichotomy is a ruse, along with implications that scientific debate on macroevolution supports assertions of supernatural design.
We often presume to know why certain things are good for us. But when it comes to lifestyles, proving what is good and why proves quite difficult.
