- The animal was about the size of a hamster.
- Researchers found teeth, a skull, jaws and some bones.
- They also found a leg bone and an arm bone.
- The animal likely climbed trees and ran on ground.

Early eukaryotes lived on ancient seafloor
Researchers studied microfossils from the McArthur and Birrindudu basins in Northern Territory, Australia, dated 1.75–1.4 billion years ago. The fossils occur mainly in oxygenated seafloor sediments, suggesting early eukaryotes needed oxygen and lived on the seafloor.
Jaw membrane in ancient Thrinaxodon may be an early eardrum
Researchers used CT scans and engineering simulations on a Thrinaxodon fossil. Their models show a membrane in the jaw could work as an eardrum, pushing the origin of sensitive mammal hearing back by nearly 50 million years.
Molecules in million‑year‑old fossils show a warmer, wetter past
Researchers extracted metabolism molecules from fossil bones aged 1.3–3 million years. Analyses of animal and plant metabolites reveal diets, infections and local environments and suggest the study sites were warmer and wetter than today.
