• Acheloids — A term given to a category or family of marine or fossil organisms, or insects in older taxonomic classifications (sometimes correlated with Coleoptera species or primitive crustaceans), whose anatomical structure resembles a fluid shape or traits historically associated with aquatic deities (Achelous). In a modern sense, the term appears in niche papers to describe specimens with a specific hydrodynamic morphology.
• Allosaurus — A genus of large bipedal theropod dinosaur, carnivorous, that lived during the Late Jurassic period (approximately 155 to 145 million years ago), operating as the apex predator in what is now North America (Morrison Formation). It was characterized by a massive skull equipped with dozens of sharp, serrated teeth, short but powerful forelimbs ending in three fingers with large claws, and a long, heavy tail used for balance.
• Anthropomorphids — A rare taxonomic or systematic name, historically used in primate classification to denote the family or extended group of higher anthropomorphic apes that present the closest structural, skeletal, and genetic similarities to humans. The study of these fossils and living specimens helps clarify the intermediate links in the hominid evolutionary tree.
