Ochotona

Anatomy

Skeleton of P. sardus

The full skeletal structure of the Sardinian pika was reconstructed in 1967, thanks to the numerous finds of bones in Corbeddu Cave, which is near Oliena, Sardinia. Some years later, from these remains, the same researchers led by paleontologist Mary R. Dawson from the US were able to create a plaster reconstruction with good accuracy, and provide a thorough description of the skeleton's morphology published in 1969.[3] The Sardinian pika was probably much stockier and more robust than extant species of pikas, and it probably resembled a sort of cross between a large wild rabbit and a pika.[3] The first articulated skeletons of P. sardus were reported in 2016.[4]

Prolagus sardus weighed about 504–525 g (17.8–18.5 oz). This is more than its ancestor Prolagus figaro, which is the only other member of Prolagus that was found in Sardinia and weighed about 398–436 g (14.0–15.4 oz), and is larger than most mainland species of Prolagus.[5]

Compared to mainland species of Prolagus, P. sardus had larger and more hypsodont (high crowned) teeth.[6][7] The Sardinian pika experienced anagenic evolution, with an increasing body size and shifting dental morphology over time.[8]

Ecology

Abundant

subfossil remains of P. sardus are known from several localities across Corsica and Sardinia hint at the once broad geographical range of this Prolagus species: it lived from sea level up to at least 800 m (2,624 ft.)[9] in a variety of habitats (grasslands, shrublands).[10] Its morphology suggests that it was capable of traversing rocky terrain, and was probably a proficient jumper and capable of digging, but was not adapted for running.[3][11] The tooth hypsodonty has been suggested to have been an adaptation to an abrasive diet.[7] The abundance of mass accumulations of broken bones (bone beds) suggest that the population density was high.[11][12][9] A sample of Late Pleistocene specimens from Medusa Cave, Sardinia found that they had a high incidience rate of arthritis relative to extant lagomorphs. This is suggested to be the result of ageing due to having a longer lifespan than mainland lagomorphs.[13] Skeletochronology suggests that individuals of Prolagus sardus reached a lifespan of approximately 8 years, which is longer than mainland lagomorphs of equivalent size.[14]

The Sardinian pika was likely preyed on by the two native species of terrestrial carnivores, a canine (the

Bubo insularis.[17]

Evolution and extinction

The taxonomy of Prolagus has been the subject of controversy. It is either considered a member of the family Ochotonidae, which includes living pikas (which all belong to the genus Ochotona), or the only member of the family Prolagidae. A partial mitochondrial genome from Prolagus sardus suggests that Prolagus is more closely related to living pikas than to Leporidae, which contains rabbits and hares, with an estimated divergence between living pikas and Prolagus about 30 million years ago.[18] The earliest species of Prolagus appeared during the Early Miocene, around 20 million years ago.[19]

The ancestor of the Sardinian pika, Prolagus figaro, arrived in the

palaeontological data has shown that the distinction made by early authors between two contemporaneous taxa (P. sardus and P. corsicanus) is probably unfounded,[22][9] as the Sardinian pika exhibits only subtle anagenetic evolution of its anatomy and body size through time.[8]

Humans first arrived in Corsica-Sardinia around 10,000 years Before Present (BP).[23] The presence of Prolagus facilitated the establishment of the first human communities of the islands. Jean-Denis Vigne found clear evidence that the Sardinian pika was hunted and eaten by people. He found that many of the Sardinian pikas' limb bones were broken and burnt at one end, suggesting that this animal had been roasted and eaten by the Neolithic colonists of Corsica.[24]

The Sardinian pika became extinct in Corsica and Sardinia sometime after 348 BC,

Tyrrhenian vole, probably also disappeared from Corsica and Sardinia around the same time.[25][23]

Historical references

The 2nd century BCE Greek historian Polybius described in The Histories the presence of an animal in Corsica locally called the kyniklos which "when seen from a distance looks like a small hare, but when captured it differs much from a hare in appearance and taste" and which "lives for the most part under the ground". This animal may have been the Sardinian pika, because Corsica at that time was not characterized by the occurrence of any species of hare.[28] The most recent zooarchaeological remains of pikas in Corsica were dated to either late pre-Roman or Roman times, between 348 BCE and 283 CE.[25]

Survival of the Sardinian pika up into

modern history has been hypothesised from the description of unknown mammals by later Sardinian authors; however, this interpretation remains dubious owing to anatomical discrepancies.[29] The Medieval Italian poet Fazio Degli Uberti mentioned "a small animal" in Sardinia which was very timid and was called "Solifughi", which means "hiding from the sun", in his 1360 poem Dittamondo ('Song of the World').[30] In 1774, Francesco Cetti wrote that the island of Tavolara off the coast of Sardinia had "giant rats whose burrows are so abundant that one might think the surface of the soil had been recently turned over by pigs", which has often been taken as a reference to the Sardinian pika.[31][32] However, this was questioned by Barbara Wilkens in a 2000 publication, who suggested that it was more likely that the animals mentioned by Cetti were brown rats.[33]
