Apatosaurus has ten dorsal ribs on either side of the body. [17] The large neck was filled with an extensive system of weight-saving air sacs. Apatosaurus, like its close relative Supersaurus, has tall neural spines, which make up more than half the height of the individual bones of its vertebrae. The shape of the tail is unusual for a ...
Comparison of three specimens and a human: Oklahoma specimen of Apatosaurus ajax (orange), A. louisae (red), and Brontosaurus parvus (green) Apatosaurines are large, long-necked, quadrupedal animals with long, whip-like tails, and forelimbs that were slightly shorter than its hindlimbs.
But a preliminary study of the relationship between adult size, growth rate, and body temperature concluded that larger dinosaurs had higher body temperatures than smaller ones had; Apatosaurus, the largest dinosaur in the sample, was estimated to have a body temperature exceeding 41 °C (106 °F), whereas smaller dinosaurs were estimated to ...
Comparative anatomy is the study of similarities and differences in the anatomy of different species. It is closely related to evolutionary biology and phylogeny [ 1 ] (the evolution of species). The science began in the classical era , continuing in the early modern period with work by Pierre Belon who noted the similarities of the skeletons ...
Comparison of three specimens and a human: Oklahoma specimen of Apatosaurus ajax (orange), A. louisae (red), and Brontosaurus parvus (green) Like those of other diplodocids, the vertebrae of the neck were deeply bifurcated on the dorsal side; that is, they carried paired spines, resulting in a wide and deep neck.

Diplodocus restored with an upright posture, based on comparison with living animals, from Taylor et al., 2009. Sauropod neck posture is a subject occasionally debated among scientists, with some favoring postures closer to horizontal whilst others a more upright posture. Research has looked at various avenues of evidence and analysis including ...
