When did life start on Earth and how do they know? Life on Earth is believed to have originated around 3.5 billion years ago, as evidenced by the discovery of microfossils and biomarkers in some of the oldest rocks on the planet. These rocks, found in places like Western Australia, provide...
Unfortunately, we don't have time machines to take us back to the time of the pterosaurs, but we do have paleontologists, scientists who study and interpret fossils. They've been able to use old rocks and bones to discover some pretty amazing things about how these creatures evolved, what...
For 130 years, we thought we understood the broad architecture of the dinosaur family tree. British palaeontologist Harry Seeley pointed out in 1887 that dinosaurs could be divided into two groups based on whether their hips were lizard-like (where the pubis points forward) or bird-...
differences in the analytical approaches used, and the rarity of high-precision geochronological dating of dinosaur fossils. Using magnetostratigraphy, cyclostratigraphy, and biostratigraphy, we establish a high-resolution
What are fossils? What are fossils and how do scientists use them? How many species have been classified? How many species do scientists estimate exist in the world today? Why is it important to maintain them? How many mature Ivory-billed Woodpeckers are estimated to exist? How many s...
Just 50 years ago, no one knew why the Earth has mountains. Now we do. This is the story of how we figured it out - and how we keep learning.
It's a dinosaur! Roar! (Do I even have to say more? It's pretty obvious what my thought process is by now.) Tyranitar -Outrage -Rock Slide -Crunch -Earthquake Godzilla gets Outrage as an Egg Move. Perfect. Slap on Rock STAB, the edgy type STAB,...

Katsuyama City, Fukui Prefecture is known nationwide as a treasure trove of dinosaur fossils. Fukui Prefectural Dinosaur Museum is one of the world's leading dinosaur museums. The vast, immersive space is filled with exhibits of dinosaur skeletons, fossils, specimens, dioramas, reconstructed models,...
Why don't we use radiocarbon dating for dinosaur bones? How do scientists know about the Triassic Period? Why are metamorphic rocks unreliable for radiometric dating? How is biology used in paleontology? Why is absolute dating used on fossils? How does photosynthesis of plants affect radiocarbon ...
