Dinosaurs thrived for 150 million years before an asteroid changed everything 66 million years ago.
In short: Explore the vast timeline of dinosaur evolution through a comprehensive data visualization. This resource maps every known fossil to reveal which groups dominated the landscape and how species like Archaeopteryx emerged, correcting common misconceptions about the true chronological distance between iconic dinosaurs.
The American Museum of Natural History provides a global map of dinosaur fossils, illustrating the incredible diversity that flourished for over 150 million years. The visualization highlights the temporal gaps between famous species, such as Spinosaurus and Stegosaurus, while tracking the rise of birds alongside their dinosaur cousins.
Complementing this, recent research from Spain has provided a rare look at stegosaur evolution. Paleontologists discovered the best-preserved stegosaur skull in Europe, belonging to Dacentrurus armatus, which lived 150 million years ago. This finding led to the definition of a new group, Neostegosauria, which includes medium and large species that spanned Africa, Europe, North America, and Asia during the Jurassic and Early Cretaceous periods.
