The Mauritian giant skink (Leiolopisma mauritiana) is a large, extinct species of skink It was found only in Mauritius. It became extinct sometime in the 17th century, likely due to human-introduced predators.

Taxonomy

The Réunion giant skink (Leiolopisma ceciliae), another extinct species, was closely related to the Mauritian giant skink. The Round Island ground skink (Leiolopisma telfairii) is a more distantly related surviving species from Mauritius.

Only a semi - complete specimen is known in addition to some odd bones. (Supposedly, a former director of the Mauritian Institute threw away specimens including some bones of this species). The remaining skeleton is missing the feet and digits, thus making it impossible for a SENI biometric analysis per se (Schnirel. 2004). The semi - complete skeleton does have a skull shaped similar to a blue-tongue skink (Tiliqua).

Description

Little is known about this species. It is believed it grew up to around 80 centimeters (31 inches) in length, making it one of the largest skinks in history. [2]

Ecology and behavior

The behavior of this animal is not well known or documented by any travelers to Mauritius when it was extant, however many things such as its diet and other aspects of its behavior can most likely be determined by extant skink species. It is very likely that the Mauritian giant skink shared behavioral traits with many other ground-based skinks such as the blue-tongued skink such as its diet and its overall temperament and speed. It may have been omnivorous, eating a diet of seeds, fruits, invertebrates and small lizards. It was also possibly capable of digging burrows. Its temperament was most likely very similar to that of modern ground skinks and was most likely a very tame animal that had relatively no fear of humans which might have played a part in its extinction.

The restoration undertaken by the (Species in Bronze Project), if accurate, gives a SENI value of .06 which would indicate that this species could have been fossorial or saxicolous in lifestyle. This is further linked by the fact that the closest living relative of this species (as mentioned by the restorers) is the Round Island ground skink (Leiolopisma telfairii). The Round Island ground skink also gives a SENI value of .06. The Round Island skink is a species capable of caudal autotomy. This skink is often seen darting in the underbrush or between rocks.

Skinks are lizards belonging to the family Scincidae, a family in the infraorder Scincomorpha. With more than 1,500 described species across 100 different taxonomic genera, the family Scincidae is one of the most diverse families of lizards. Skinks are characterized by their smaller legs in comparison to typical lizards and are found in different habitats except arctic and subarctic regions.

<i>Eugongylus</i> Genus of lizards

Eugongylus is a genus of skinks in the subfamily Eugongylinae. It was previously recognised as namesake of the Eugonglyus group of genera within Lygosominae, where it occupied a quite basal position. Members of this genus are commonly called mastiff skinks or short-legged giant skinks.

<i>Leiolopisma</i> Genus of lizards

Leiolopisma is a genus of skinks. Most species occur in the region of New Caledonia-New Zealand, and they are related to other genera from that general area, such as Emoia; these and others form the Eugongylus group. One living and two extinct taxa represent a clade endemic to the Mascarenes.(Austin & Arnold 2006)

<span class="mw-page-title-main">Blue-tongued skink</span> Genus of lizards

Blue-tongued skinks comprise the Australasian genus Tiliqua, which contains some of the largest members of the skink family (Scincidae). They are commonly called blue-tongued lizards or simply blue-tongues or blueys in Australia or panana in Indonesia. As suggested by these common names, a prominent characteristic of the genus is a large blue tongue that can be bared as bluff-warning to potential enemies. The type of predator/threat that is near will determine the intensity of colour present in the tongue. The tongue can also deform itself and produce a thick mucus in order to catch prey. They are relatively shy in comparison with other lizards, and also significantly slower due to their shorter legs.

The broad-billed parrot or raven parrot is a large extinct parrot in the family Psittaculidae. It was endemic to the Mascarene island of Mauritius. The species was first referred to as the "Indian raven" in Dutch ships' journals from 1598 onwards. Only a few brief contemporary descriptions and three depictions are known. It was first scientifically described from a subfossil mandible in 1866, but this was not linked to the old accounts until the rediscovery of a detailed 1601 sketch that matched both the subfossils and the accounts. It is unclear what other species it was most closely related to, but it has been classified as a member of the tribe Psittaculini, along with other Mascarene parrots. It had similarities with the Rodrigues parrot, and may have been closely related.

The Mauritius sheldgoose, also known as the Mauritius shelduck, is an extinct species of sheldgoose that was endemic to the island of Mauritius. While geese were mentioned by visitors to Mauritius in the 17th century, few details were provided by these accounts. In 1893, a carpometacarpus wing-bone and a pelvis from the Mare aux Songes swamp were used to name a new species of comb duck, Sarcidiornis mauritianus. These bones were connected to the contemporary accounts of geese and later determined to belong to a species related to the Egyptian goose and placed in the sheldgoose genus Alopochen. The Mauritius and Réunion sheldgoose may have descended from Egyptian geese that colonised the Mascarene islands.
