400 million-year-old fish fossils reveal how life began moving onto land

Australia China fossil formation skull

Scientists have uncovered new clues about some of Earth’s earliest fish, shedding light on the ancient origins of vertebrates that eventually moved onto land. By reanalyzing mysterious fossils from Australia’s famed Gogo Formation and studying a newly reconstructed 410-million-year-old lungfish skull from China, researchers are revealing how these primitive creatures evolved.

Triceratops had a giant nose that may have cooled its massive head

fossil Triceratops CT-scan skull

Triceratops’ massive head may have been doing more than just showing off those famous horns. Using CT scans and 3D reconstructions of fossil skulls, researchers uncovered a surprisingly complex nasal system hidden inside its enormous snout. Instead of being just a supersized nose for smelling, it likely housed intricate networks of nerves and blood vessels—and even special structures that helped regulate heat and moisture.

This ancient animal was one of the first to eat plants on land

tooth fossil skull

Hundreds of millions of years ago, the first animals to crawl onto land were strict meat-eaters, even as plants had already taken over the landscape. Now scientists have uncovered a 307-million-year-old fossil that rewrites that story: one of the earliest known land vertebrates to start eating plants. The animal, named Tyrannoroter heberti, was a stocky, football-sized creature with a skull packed with specialized teeth designed for crushing and grinding vegetation.

This strange little dinosaur is forcing a rethink of evolution

bone tooth metabolism Dinosauria Foskeia anatomy bird evolution mammals study skull

A newly identified tiny dinosaur, Foskeia pelendonum, is shaking up long-held ideas about how plant-eating dinosaurs evolved. Though fully grown adults were remarkably small and lightweight, their anatomy was anything but simple—featuring a bizarre, highly specialized skull and unexpected evolutionary traits. Detailed bone studies show these dinosaurs matured quickly with bird- or mammal-like metabolism, while their teeth and posture hint at fast, agile lives in dense forests.
