Descrizione
English: A size comparison between the one of the largest sauropod dinosaurs, Patagotitan mayorum, and various large land mammals, living and extinct; a Polar Bear, the largest extant carnivorous land mammal; a Giraffe, the tallest extant land mammal; an African Elephant, the largest extant land mammal; a White Rhino, the second largest land mammal (excluding other elephant species); the extinct Rhinocerotoid Paraceratherium transouralicum, one of the largest land mammals ever to have existed and the large extinct elephant Palaeoloxodon recki.



Patagotitan is one of the largest sauropod dinosaurs known from relatively complete remains.[1] Mounted skeletons are on display at American Museum of Natural History and The Field Museum of Natural History. Patagotitan silhouette based on a reconstruction by Henrique Paes, used with permission.[2]
Palaeoloxodon recki silhouette redrawn from Appendix 1 T in Larramendi 2016. Palaeoloxodon, along with Stegodon and Mammuthus, were among some of the largest land mammals. One fragmentary individual of Palaeoloxodon namadicus, known from a partial femur (Sagauni II), possibly belongs to the largest land mammal currently known. However, the exact size estimation has some uncertainty and has not been shown here.[3]
Paraceratherium silhouette redrawn from Appendix 1 AG in Larramendi 2016. The largest individuals are known from fragmentary remains (i.e. AMNH 26168/75) and there is some uncertainty as to the estimated body size.[3]
• Polar Bear silhouette has been primarily redrawn from a personal photo taken in Copenhagen Zoo. One male specimen was reported as 2.85 m long with a shoulder height of 1.7 m.[4]
• Giraffe silhouette has been primarily based on the proportional information in Cavener et al. (2024).[5] Scaled to be ~5.87 m tall, the reported height a large male giraffe, measured 'between pegs' (i.e. stretched out). Taller heights have been claimed, but these are not as credible or unauthenticated.[6][7] Note: The giraffe illustrated here is scaled to be 5.87 m when posed with the neck fully vertical to the top of the ossicones. However, due to some uncertainty over the specifics of how this giraffe was measured, there could be some slop in the scale here.
• Elephant silhouette primarily redrawn from a photo by Ian Sewell.[8] The silhouette is scaled to have a shoulder height of ~3.2 m, the average height for adult male elephants. Adult females are smaller on average, being around ~2.6 m tall at the shoulder. The reported shoulder height of the largest accurately measured male elephant is over 4 m when laid out on the ground, estimated to be ~3.96 m when standing. Such large individuals are, however, extremely rare.[3]
• Rhino silhouette is primarily redrawn from a photo by user Ikiwaner.[9] Scaled to have a shoulder height of ~1.86 m.[10]
• Humans scaled to 170 cm (5 ft 7 in) and 160 cm (5 ft 3 in) respectively.
