Coniferous forest would have been a more accurate biome. Its status as a deciduous forest animal is incorrect, since deciduous, broad-leafed trees did not exist when Apatosaurus was alive.It wasn't until 2015, several years after Dinosaur Digs was released, that Brontosaurus was declared a valid genus again after further studies suggested it was different enough from the original Apatosaurus finds. Apatosaurus and Brontosaurus were initially treated as separate genus until studies suggested that Brontosaurus was simply a species of Apatosaurus. Apatosaurus is referred to as Brontosaurus at the start of its in-game description.Apatosaurus is the largest land-animal in the Zoo Tycoon series, although it is surpassed by the Lion's Mane Jelly and Sperm Whale in terms of length and weight, respectively.These four can only kill staff members if they escape their exhibit.
