Patagotitan (jun 26, 101620000 BC – apr 10, 101000000 BC)

Description:

Patagotitan is a genus of titanosaurian sauropod from the Cerro Barcino Formation in Chubut Province, Patagonia, Argentina. The genus contains a single species known from multiple individuals: Patagotitan mayorum, first announced in 2014 and then validly named in 2017 by José Carballido, Diego Pol and colleagues. Contemporary studies estimated the length of the type specimen, a young adult, at 37 m (121 ft)[1] with an approximate weight of 69 tonnes (76 tons).

Research as of 2017 estimated Patagotitan mayorum to have been 37 m (121 ft) long,[1] with an approximate weight of 69 tonnes (76 tons).[2] These findings represented a refinement of initial estimates that placed the taxon's adult size at 40 m (131 ft) long with a weight of 77 tonnes (85 tons);[3][1] science writer Brian Switek had cautioned in 2014 that it was still too early to make size estimates with the desirable scientific certainty.[4]
The Patagotitan taxon stands as readily comparable in size to the next largest titanosaur taxon, Argentinosaurus, estimated at 73–96.4 tonnes (80.5–106.3 tons) by some studies[5][6][7] and thus one of the largest land animals in Earth's history.
