“Brachiospinus Altus: The River Giant of the Mid-Cretaceous”

First documented in the Kem Kem beds of North Africa, Brachiospinus altus was a towering semi-aquatic herbivore that roamed floodplains 100 million years ago. This rare hybrid species combined the elongated neck and forelimb-dominant stance of Brachiosaurus with the iconic sail of Spinosaurus aegyptiacus. Standing over 50 feet long, its sail likely served for thermoregulation and display, while its powerful limbs allowed it to wade through shallow waters in search of vegetation. Fossilized impressions reveal a mottled skin pattern of ochre, green, and rust, ideal for camouflage among reeds and riverbanks. Though peaceful in nature, its sheer size and tail strength made it a formidable presence. Brachiospinus reshapes our understanding of sauropod adaptation in aquatic ecosystems.
