Daxiatitan binglingi is a large sauropod dinosaur discovered in Gansu province, China. It's a basal titanosaur closely related to Euhelopus, but with more derived features.
The recovered remains include 22 vertebrae (10 cervicals, 10 dorsals, and 2 caudals), partial cervical and dorsal ribs, one hermal arch, right scapulocoracoid, and right femur. Only 6 vertebrae are photographed and published in the paper, and both the right scapulocoracoid and femur are not shown in right laterally view unfortunately. So I have only illustrated the bones with photographic material in my drawing in white. The grey vertebrae are either not preserved or not shown in photos/drawings, and I am making no attempt to draw them here. The drawing of the right scapulocoracoid does not
include much detail since I do not have a right laterally view of the fossil. Also the femur is shown only in posterior view above the silhouette in a weird placement in the drawing due to the same reason
As suggested, Daxiatitan is closely related to Euhelopus, so I have assumed the same vertebral construction for Daxiatitan based mainly based on the photos and measurements included in the original description paper, as well as drawing published by Wiman, C. in 1929 on Euhelopus. Contrary to the paper by You can co., who suggests a total of 19 cervicals and 12 dorsals for Euhelopus, I reconstructed it with 17 cervicals and 14 dorsals. So the recovered 10 caudal most cervicals are C8 to C17. The longest of the cervicals is the 7th to last, C11, which is also consistent in Euhelopus. So the C18 as suggested in the Daxiatitan paper is actually placed as D1 here. Hence, the published photos of all the cervicals in the paper are positioned as C11, D1, and D3 in my drawing. The position of the two fused posterior dorsal vertebrae are not 100% certain due to missing dorsals. I have placed them as D7 and D8. And the isolated dorsal as D14, the last dorsal as suggested in the paper. The position of one of the better preserved isolated caudal is kinda arbitrary since I have no idea where to place it other than in the front half of the tail.
Though it's a close relative to Euhelopus, Daxiatitan actually has quite different proportions. The scapulocoracoid is not nearly as large proportionally as in Euhelopus. So the shoulders are not positioned as high, and the back should be more horizontal in Daxiatitan. However, it seems to have a more elongated neck about three times as long as Euhelopus', about 12 meters long. Despite the huge neck, it's not ridiculously tall due to the shoulder height, which is around 4.5 meters. The entire length of the animal is about 25 to 27 meters, depending on the size of the tail. My drawing shows a pretty long tail so it's more close to 27 meters in length.
This is my first attempt at creating an dinosaur skeletal reconstruction drawing. It seems like Daxiatitan, being quite tall and lengthy, might not have been very massive. I estimate the mass to be somewhere between, 25000 to 30000 kgs, a little less than the holotype of Giraffatitan, not a super heavy weight by sauropod standard.
This is my first attempt at creating a dinosaur skeletal construction drawing. I am still learning about dinosaur bone morphologies in general so there might be mistakes in the drawing, and I welcome all constructive criticisms.
