In 1923, scientists from the American Museum of Natural History unearthed the first fossils to be widely regarded as dinosaur eggs. Found in the Gobi Desert in Mongolia, the eggs were initially thought to belong to Protoceratops, whose remains were frequently found in the area.

October 30, 2025 - Skeletons of duck-billed dinosaurs found more than 100 years ago are so well-preserved that they contain fleshy body parts of the extinct species embedded in thin layers of clay, scientists say. Specimens of Edmontosaurus annectens, known for their long skull that resembles a duck's bill, were found in eastern Wyoming in the early 1900s. Recent reexamination of those fossils by paleontologists at the University of Chicago revealed that the fossils do not contain just bones, but mummified body parts protected underneath a clay mask, according to a paper published last week in Science.

1 month ago - Damage to the back end of the skull was interpreted early on as a fatal bite wound, but subsequent study by Field Museum paleontologists found no bite marks. The distortion and breakage seen in some of the bones in the back of the skull was likely caused by post-mortem trampling. Sue's cause of death is ultimately unknown. The dinosaur died in a seasonal stream bed, which washed away some small bones as it rapidly covered the remains with sediment, ultimately leading to fossilization.

October 29, 2025 - Called clay templating, the external fleshy surface of the dinosaur was preserved over the skeleton after burial by a thin clay mask no more than 1/100th of an inch thick. Using an array of imaging techniques, the scientists reconstructed the fleshy appearance of the animal in life, from a tall crest over the neck and trunk to a spike row over its tail and hooves sheathing its toes. Combined with fossilized footprints, the appearance of a duck-billed dinosaur—long guessed at but never demonstrated in this detail—is now at hand.
