Tarchia was a medium-sized ankylosaur, measuring around 5.5–6 metres (18–20 ft) long and weighing up to 2.5–3 metric tons (2.8–3.3 short tons). [9] [10] If ZPAL MgD I/113 indeed belongs to the genus, it would have belonged to an individual measuring 5.8–6.7 metres (19–22 ft) long.
The generic holotype, consisting of broken teeth, jaws, and a skull was discovered by a pastoralist, William Avery, near Lake Colungolac from which the species Thylacoleo carnifex was described by Richard Owen. [2] It was not until 1966 that the first nearly-complete skeleton was found. The only pieces missing were a foot and the tail.
Their skulls measure 1.4–1.7 centimetres (0.55–0.67 in) in length, indicating that Oculudentavis would have been comparable in size with the modern bee hummingbird if it were an avialan. Both specimens were retrieved from 99-million-year-old deposits of the Hukawng Basin in Kachin State , northern Myanmar .
Initially, Nanuqsaurus was estimated to have been about 5–6 meters (16–20 ft) long, a metric based on the holotype specimen, putting the animal at about half the length of Tyrannosaurus rex. [5] [6] [7] The length of the same specimen's reconstructed skull, based on the proportions of related animals, was 60–70 cm (24–28 in). [3]
A study on the anatomy of the skull and on the neurology of Tarjadia ruthae is published by Desojo et al. (2024). [ 20 ] A study on the humeral bone histology of Benggwigwishingasuchus eremacarminis is published by Klein (2024), who finds no evidence of secondary aquatic adaptations, but reports evidence indicative a slower growth rate than in ...
