FIG. 6 in Reassessment Of A Historical Collection Of Sauropod Dinosaurs From The Northern Morrison Formation Of Wyoming, With Implications For Sauropod Biogeography

FIG. 6. Range of midcaudal centrum elongation in Morrison Formation sauropods. Ratio represents centrum length (cL) to posterior centrum height (pcH). Dots are ratios of single vertebrae, bars represent the range of means from individual specimens, and stars are the mean of the specimen means across the entire taxon. The dotted line in Apatosaurinae indet. indicates that the highest value (1.8) comes from a specimen represented by a single vertebra in this dataset (LACM 52844), whereas several other, more complete specimens all have values that range between 1.2 and 1.3 (represented by the continuous bar). The open rectangles represent ratios in specimens from RFPR (CM 312 and CM 36034 may be from a single individual, see text). Note the generally higher mean values of diplodocines (Supersaurus, Galeamopus, Diplodocus, Barosaurus) compared with apatosaurines (Apatosaurus, Brontosaurus, and indeterminate specimens) with the exception of LACM 52844. The RFPR specimens are colored as the taxon to which they are referred in the text, with the exception of CM 312 and CM 36034, which are referred to Neosauropoda indet.
