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.

[8] Abundant fossil and 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).

[18]Rodentia Leporidae (rabbits and hares) †Prolagus Ochotona (living pikas) The earliest species of Prolagus appeared in Europe during the Early Miocene, around 20 million years ago.

[19] The ancestor of the Sardinian pika, Prolagus figaro, arrived in the Corsican-Sardinian microcontinent at the early-late Pliocene boundary around 3.6 million years ago, likely due to an emergent land connection with Italy caused by a sea level drop.

[21] The oldest unambiguous remains of Prolagus sardus date back from the Middle Pleistocene,[12] a time when both islands were periodically connected due to sea level changes.

Reassessment of 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.

[23] Its extinction was possibly due to agricultural practices, the introduction of predators (dogs, cats and small mustelids) and ecological competitors (rodents, rabbits and hares).

[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.
