Yongjinglong datangi skeletal reconstruction (old)

NOTE: This reconstruction is defunct and outdated. The newer skeletal reconstruction can be found here.

Yongjinglong datangi (Dragon from Yongjing, of the Tang Dynasty) is a species of titanosauriform sauropodomorph that lived during the Early Cretaceous in what is now China. Its most distinctive feature is its very long shoulder blade, which would have given it a very deep chest in life.

Here is the first Yongjinglong skeletal aside from the one in the description paper itself. This skeletal assumes that the description paper's skeletal is correct regarding the relative positions of the bones.

Most of the vertebrae were crushed, and I had to uncrush them using the relatively intact posterior dorsals as a basis.

The gaps in dorsal vertebra series were filled in with speculative dorsals based on the adjacent vertebrae. The size and number of speculative vertebra filling a gap is based on the amount of space between the preserved dorsals.

The hips, tail, humerus, hindlimbs, feet, and sternal plate were based on Opisthocoelicaudia. The ribs were generic ribs very loosely based on Opisthocoelicaudia.

The neck and the head size are restored using Saltasaurus as a base, and the head is based off that of Nemegtosaurus.

The foreclaws and the gastralia were inferred from Diamantinasaurus and Jobaria respectively, and are represented as generic claws and gastralia.

UPDATE(6/14/2015): Tweaked the scaling of the skull and the cervicals. Apparently the overly small head came about due to me scaling the Alamosaurus parts to match the length of the Yongjinglong cervical, despite the Yongjinglong cervical having a centrum with a diameter roughly a third greater than the centrum diameter of the corresponding cervical of Lehman & Coulson's Alamosaurus.

I thus adjusted the cervicals to match both length and centrum diameter. The adjusted cervicals ended up too big for the previous skull, so I increased the skull's dimensions by roughly ~33%. The larger head increased standing length to ~15.85 meters from 15.7 meters, and axial length from ~17.86 meters to ~18.01 meters.

The previous version can be found here for comparison and contrast. The head should be closer to normal now.
Still weird overall though.


UPDATE(8/15/2015): Rescaled the bones based on the measurements from Li et al. and rearranged the bones to accommodate the different proportions. The comment by prompted me to recheck the paper's scaling, and the scaling in the Li et al. paper turned out to not match it's own measurements.

It ended up quite a bit smaller and more compact, and it managed to get even weirder than before. And while the hindlimbs in the previous versions were huge compared to the forelimbs, this time, it's the other way around...
Previous version for comparison and contrast

Measurements of the previous version, also for comparison and contrast:
~3.68 meters hip height, ~3.6 meters shoulder height, ~3.6 meters dorsal series length, ~15.85 meters standing length, ~4.2 meters torso length, ~18 meters axial length


UPDATE(12/24/2015): Redrew the cervical series based on the adult Alamosaurus cervicals. The hips and hindlimbs rescaled based on the forelimbs rather than the vertebral centra height.
Previous version for comparison and contrast

Measurements for previous version:
~2.26 meters hip height, ~2.7 meters shoulder height, ~5.4 meters total height, ~2.36 meters dorsal series length, ~8.57 meters standing length, ~3.2 meters torso length, axial length unmeasured

UPDATE(12/27/2016): A whole new skeletal, with almost none from the previous versions carried over. The neck and the proportional size of the head is based on Greg Paul's Saltasaurus skeletal  
Previous version for comparison and contrast

Measurements for previous version: ~2.25 meters hip height, ~2.82 meters shoulder height, ~5.36 meters total height, ~2.36 meters dorsal series length, ~9.5 meters standing length, ~3.2 meters torso length, ~10.9 meters axial length

UPDATE(2/17/2017): Fixed a layering order issue in the cervical-dorsal transition and the dorsals.
