Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. S. Malkani 2023 | Ikqaumishan smqureshi medium sized sauropod shares with the Titanosauria on the basis of procoelous caudal vertebrae which are found from this upper Sangiali (south Sangiali) locality. It shares with Poripuchia because of sharing with Gspsauridae. It shares with Gspsauridae on the basis of medially inset and almost straight deltopectoral crest. Its autapomorphy shown as; Ikqaumishan smqureshi has medially inset, slender and almost straight deltopectoral crest and strong medial expansion of medial process of proximal humerus (Figure 13), while this prominent medially expanded medial process is not found in any Indo-Pakistani titanosaurs. Its deltopectoral crest is more slender (and straight) than the slender deltopectoral crest of Gspsaurus pakistani, intermediate (between slender and robust) and sinusoidal deltopectoral crest of Imrankhanhero zilefatmi (and may be Isisaurus colberti) and robust deltopectoral crest of Qaikshaheen masoomniazi and Pakisaurus balochistani. Its deltopectoral crest is relatively thin at the base/ventral portion than the deltopectoral crest of Gspsaurus pakistani specimen NHMUK R5931 from Chhota Simla ([51], page 289; [52], page 1045; ([27], see Table 3; [62], page 459) which are more thick and sub-circular shaped peak forming. Its humerus has posteriorly plain surface while Pakisaurus balochistani has posterior ridge just below the head with triceps fossae. |
