Apex (dinosaur)
"Apex" is a fossilized specimen of an unknown species in the genus ''Stegosaurus'', discovered in Colorado's Morrison Formation in 2022. Dated to the Late Jurassic epoch, it is the largest known ''Stegosaurus'' fossil, preserving skin impressions and throat ossicles alongside a mostly complete skeleton. On July 17, 2024, the specimen was sold at Sotheby's for $44.6 million to hedge fund billionaire Kenneth C. Griffin, making it the List of dinosaur specimens sold at auction, highest-priced fossil ever sold at auction. The sale sparked debate among paleontologists regarding the purchase by private individuals of specimens with high scientific value. In December 2024, the fossil was loaned to the American Museum of Natural History, and is planned to be exhibited there for four years. Researchers aim to identify Apex's species, and study its growth pattern. Description Apex is the largest and most complete known ''Stegosaurus'' skeleton , with 254 bones preserved out of app ...

Stegosaurus
''Stegosaurus'' (; ) is a genus of herbivorous, four-legged, armored dinosaur from the Late Jurassic, characterized by the distinctive kite-shaped upright plates along their backs and spikes on their tails. Fossils of the genus have been found in the western United States and in Portugal, where they are found in Kimmeridgian- to Tithonian-aged strata, dating to between 155 and 145 million years ago. Of the species that have been classified in the upper Morrison Formation of the western US, only three are universally recognized: ''S. stenops'', ''S. ungulatus'' and ''S. sulcatus''. The remains of over 80 individual animals of this genus have been found. ''Stegosaurus'' would have lived alongside dinosaurs such as '' Apatosaurus'', '' Diplodocus'', '' Camarasaurus'' and '' Allosaurus'', the latter of which may have preyed on it. They were large, heavily built, herbivorous quadrupeds with rounded backs, short fore limbs, long hind limbs, and tails held high in the air. Du ...
