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 redrawn from a photo by user GTBacchus.^[5] with modifications to make it look like a male. Scaled to be ~5.88 m tall, the reported height of the tallest 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 5.88 m when posed with the neck fully vertical with the head extended. However, due to some uncertainty, 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.
