Fossil reveals 'cute' baby dinosaur's skull features

A rare titanosaur embryo was discovered with its skull preserved in 3 dimensions.

Kundrát et al., Current Biology, 2020
  • Researchers have uncovered what the facial features of a baby titanosaurus embryo looked like using cutting-edge imaging technology.
  • This in the first-ever discovery of a 3D embryonic titanosaurian sauropod skull.
  • The embryo reveals that titanosaur babies had binocularly focused vision in the front of the head rather than on each side, retracted openings on their snout, and a single horn in the front of their head.

  • The triceratops skull was first discovered in 2019, but was excavated over the summer of 2020.
  • It was discovered in the South Dakota Badlands, an area where the Triceratops roamed some 66 million years ago.
  • Studying dinosaurs helps scientists better understand the evolution of all life on Earth.

Rare fossil depicting battle sheds light on ancient ant

Fossils depicting animals in action are very rare.

Barden et al., Current Biology, 2020
  • A fossil of a prehistoric ant hunting has recently been discovered.
  • Fossilization is rare, so depictions of activities like hunting are hard to come by.
  • Other fossils show us how dinosaurs hunted, fought, and died.

Dinosaurs suffered from cancer, study confirms

A recent analysis of a 76-million-year-old Centrosaurus apertus fibula confirmed that dinosaurs suffered from cancer, too.

  • The fibula was originally discovered in 1989, though at the time scientists believed the damaged bone had been fractured.
  • After reanalyzing the bone, and comparing it with fibulas from a human and another dinosaur, a team of scientists confirmed that the dinosaur suffered from the bone cancer osteosarcoma.
  • The study shows how modern techniques can help scientists learn about the ancient origins of diseases.

This might be the oldest creature to have ever lived on land

Scientists think an insect similar to the modern millipede crawled around Scotland 425 million years ago, making it the first-ever land-dweller.

British Geological Survey
  • An ancient millipede-like creature living in Scotland may have been the first creature to live on land.
  • A fossil representing Kampecaris obanensis was first discovered in 1899 on the Scottish isle of Kerrera. It's now been radiometrically dated to 425 million years ago.
  • If the new research is correct about the age of the fossil, then scientists have been greatly underestimating how rapidly bugs and plants evolved to transition to life on land.
