Walk-through: AMNH’s Impact exhibit on the asteroid that doomed the dinosaurs
Overview: A multidisciplinary journey into the dinosaur extinction In New York City, the American Museum of Natural History opens a bold new exhibition that looks at the asteroid strike credited with ending the reign of the non-avian dinosaurs. The Impact exhibit invites visitors to move beyond a single narrative, weaving together geology, paleontology, archaeology, climate…

Humans Driving Extinctions at Rates Not Seen Since the Dinosaurs, Scientists Warn
Humanity’s Role in a Rapid Biodiversity Crisis New research synthesizing decades of environmental data and paleobiology suggests that humans are triggering the most rapid biodiversity loss since the asteroid wipeout that ended the age of the dinosaurs. While the current pace of species extinctions is extraordinary, scientists say we have not yet crossed the threshold…

Humans Driving Extinctions On a Scale Not Seen Since the Dinosaurs, Scientists Warn
Human activity pushes biodiversity toward a historic crossroads New research suggests that human activity is triggering an extinction episode on a scale not seen since the dinosaur era. While not yet classified as a true mass extinction, scientists say the current rate of species loss is extraordinarily high and could become irreversible if biodiversity loss…

Humans Driving Extinctions On a Scale Not Seen Since Dinosaurs, Scientists Say
Human activity may trigger the greatest extinction event since the dinosaurs New research synthesizes decades of environmental data and expert workshops to argue that human activity is driving biodiversity loss at a pace that rivals the most dramatic extinction events in Earth’s history. While the study stops short of labeling today’s declines as a true…

Giant Dinosaurs Were Riddled With a Devastating Disease, Fossils Show
Introduction to Dinosaur Health Issues Dinosaur life, often portrayed as a vibrant age of massive creatures, wasn’t always idyllic. Recent studies reveal that many dinosaurs were affected by debilitating diseases long before the catastrophic Chicxulub asteroid impact that ended the Mesozoic era. Among the most alarming findings is evidence of a potentially deadly bone disease…
