Hagryphus (meaning "Ha's griffin") is a monospecific genus of caenagnathid dinosaur from southern Utah that lived during the Late Cretaceous (upper Campanian stage, 75.95 Ma) in what is now the Kaiparowits Formation of the Grand Staircase–Escalante National Monument. [1]
In 2010, fossils of butchered animal bones dated 3.4 million years old were found in Ethiopia, close to regions where australopith fossils were found. [56] However, a 2025 study measuring nitrogen isotope ratios in fossilized teeth determined that Australopithecus was almost entirely vegetarian.
Ceratopsia or Ceratopia (/ ˌ s ɛr ə ˈ t ɒ p s i ə / or / ˌ s ɛr ə ˈ t oʊ p i ə /; Greek: "horned faces") is a group of herbivorous, beaked dinosaurs that thrived in what are now North America, Asia and Europe, during the Cretaceous Period, although ancestral forms lived earlier, in the Late Jurassic of Asia.
Diabloceratops (/ d aɪ ˌ æ b l oʊ ˈ s ɛr ə t ɒ p s / dy-AB-loh-SERR-ə-tops) is an extinct genus of centrosaurine ceratopsian dinosaur that lived approximately 81.4-81 million years ago during the latter part of the Cretaceous Period in what is now Utah, in the United States. [1]
Excavation site at Dmanisi in 2007. Dmanisi is located in southern Georgia, about 85 kilometres (52.8 miles) from the country's capital, Tbilisi.It was founded as a city in the Middle Ages and has thus been a site of archaeological interest for some time, with a prominent archaeological excavation site being located within the ruins of the old city on a promontory overlooking the Mashavera and ...
Bone fragments unearthed in a cave in central Germany show that our species ventured into Europe's cold higher latitudes more than 45,000 years ago - much earlier than previously known - in a ...
The bones of the skull roof were fused and by a folding of the frontal bones, a "double" skull roof was created. In Triceratops, some specimens show a fontanelle, an opening in the upper roof layer. The cavity between the layers invaded the bone cores of the brow horns. [30] Back of skull, showing rounded joint which connected the head and neck
Giganotosaurus was one of the largest known terrestrial carnivores, but the exact size has been hard to determine due to the incompleteness of the remains found so far. Estimates for the most complete specimen range from a length of 12 to 13 m (39 to 43 ft), a skull 1.53 to 1.80 m (5.0 to 5.9 ft) in length, and a weight of 4.2 to 13.8 t (4.6 to ...
