Scientific discoveries reveal prehistoric eggs, terror birds, and long-lived sturgeons

Recent paleontological and biological findings have provided new insights into prehistoric life and species longevity. In Antarctica, researchers discovered a 68-million-year-old fossilized egg, named ‘Antarcticoolithus bradyi’. Measuring approximately 29 cm by 20 cm, it is the second largest egg ever found and the largest known soft-shelled egg. While no skeleton was found, paleontologists suggest the egg may belong to a mosasaur, a large marine reptile, potentially supporting theories that these creatures were viviparous.

In South America, fossils of the Phorusrhacidae family, known as terror birds, have revealed the dominance of these two-meter-tall predatory birds following the extinction of dinosaurs. These flightless carnivores utilized powerful legs and sharp beaks to occupy the top of the food chain in ancient savannas and forests.

Additionally, new scientific evaluations of the sturgeon have overturned previous biological understandings. While scientists once believed these fish lived up to 150 years, modern statistical models indicate that adult females can exceed 400 years of continuous existence.
