Our universe is about 13.8 billion years old, and the observable bubble of that cosmos has a diameter of about 93 billion light-years across. And we all know the famous maxim from Albert Einstein’s special theory of relativity: nothing can travel faster than light.Taken together, this presents us with a perplexing riddle about the nature of the cosmos itself: How can the universe get so mind-bogglingly big in such a short amount of time?What Does "Faster Than Light" Mean?There are two ways to ...read more
A mat composed of microbes may have preserved a series of 255-million-year-old indentations made in a sandy South African tidal bottom by a hulking amphibian, a new study says.The remarkable shapes reveal that the nearly 2-meter-long rhinesuchid temnospondyl lurked for its prey and swam after it in the fashion of a crocodile. Like a prehistoric choreographer’s diagram, the impressions are a unique window into life on ancient earth shortly before the Permian Mass Extinction Event destroyed 90 p ...read more

So, what, specifically, do paleontologists do, and why is their work so important?What Is Paleontology?In the si ...read more
Dinosaurs lived relatively long lives. The oldest Tyrannosaurus rex specimens that we’ve found were alive for about 30 years. It’s likely that many dinosaurs, especially sauropods, lived much longer than that. And with long lives and aging comes diseases. But what do we know, and what can we know about the diseases that impacted our favorite dinosaur species?According to Penélope Cruzado-Caballero, an assistant professor of paleontology at the University of La Laguna in Spain, dinosaurs ...read more
