Brontosaurus excelsus (Marsh, 1879)Sauropsida
Wyoming and Utah, United States
Length: 22 m
If you needed further evidence that the Linnaean taxonomic system is broken and needs replacement, then Old Bronty here is your Huckleberry. More than a century after her genus was synonymized with Apatosaurus in 1903, a new study in 2015 revalidated Othniel Charles Marsh's original description of Brontosaurus being phylogenetically distinct from Apatosaurus (Apatosaurus had a fatter neck). Brontosaurus lives again!
