Summary

Description
English: Skeletal diagram featuring the skull holotype of the ankylosaur Tsagantegia longicranialis. It was discovered and unearthed from the Bayan Shireh Formation of Mongolia, at the locality of Tsagan Teg, and described in 1993 by the Russian paleontologist Tatyana Alekseyevna Tumanova. Although only having one element, its skull is pretty much complete.[1] Comparisons with Talarurus indicates niche partitioning between these genera, Tsagantegia being a browser, and Talarurus a grazer.[2]

Apparently, Tumanova has measured its skull at 30 cm (300 mm)[1][3], however, it seems that the actual length is about 38 cm (380 mm), as indicated by Arbour & Currie 2015.[4] In addition, the figured skull appears to be a "reconstructed" line drawing, and not a direct illustration of the fossil. The lateral view here has been based on James I. Kirkland, featuring the real fossil.[5] Nevertheless, the estimated size, 6 m (20 ft), is following Tumanova 2000, which seems to fit the size of the skull.[3]

Overall anatomy based on Jack Mayer Wood.

Español: Diagrama esquelético mostrando el holotipo craneano del ankylosaurio Tsagantegia longicranialis. Fue descubierto y desenterrado desde la Formación Bayan Shireh de Mongolia, en la localidad Tsagan Teg, y descrito en 1993 por la paleontóloga rusa Tatyana Alekseyevna Tumanova. Aunque solo tiene un elemento, su cráneo esta bastante completo. Comparaciones con Talarurus indican partición de recursos entre estos géneros, Tsagantegia siendo ramoneador, y Talarurus un pacedor.

Aparentemente, Tumanova a medido su cráneo en 30 cm (300 mm), sin embargo, parece ser que en realidad el largo es de entre 38 cm (380 mm), como se indica en Arbour & Currie 2015. En adición, el cráneo figurado parece ser un boceto "reconstruido", y no una ilustración directa del fósil. La vista lateral de este diagrama ha sido basada en James I. Kirkland, mostrando el fósil real. No obstante, el tamaño estimado, 6 m (20 pies), sigue a Tumanova 2000, tamaño que parece concordar con el cráneo.
