Deinogalerix (from Ancient Greek, "terrible/terror" + Galerix ) is an extinct genus of gymnure which lived in Italy in the Late Miocene, 7-10 million years ago. The genus was apparently endemic to what was then the island of Gargano, which is now a peninsula in southeastern Italy bounded by the Adriatic Sea. The first specimens of Deinogalerix were first described in 1972. [5]

The genus is in the hedgehog subfamily of gymnures or moon-rats, which are not rats at all, but rather hairy, superficially rat-like relatives of the hedgehog lacking quills. Deinogalerix had a long, thin, conical face, small pointed ears, a lengthy, tapering tail and long hairs. [6]

D. koenigswaldi's skull was 21 centimetres (8.3 in) long and the entire body measured 60 centimetres (24 in). It occupied the same ecological niche as dogs and cats today. It shared this niche with the enormous barn owl Tyto gigantea . [1]

It is believed that the species of Deinogalerix were insectivores, mostly feeding off invertebrates like beetles, dragonflies and crickets, and possibly even snails. But the larger species may also have scavenged on small mammals, reptiles and birds. [7]

In the Late Miocene subepoch, what is at present Italy was mainly a group of small islands and only at a later date did majority of these join with the mainland. It is known that animals on these islands sometimes evolved quite differently from elsewhere. So it is possible that Deinogalerix may have lived exclusively in the Gargano.[ citation needed ]

Gymnures, also called hairy hedgehogs or moonrats, are mammals belonging to the subfamily Galericinae, in the family Erinaceidae and the order Eulipotyphla. Gymnures resemble rats but are not closely related as they are not rodents; they are instead closely related to hedgehogs, which also belong to Erinaceidae. They are thought to have appeared in Eastern Asia before their closest relatives, and changed little from the original ancestor, which is thought to have been also the ancestor of the shrews.

<span class="mw-page-title-main">Erinaceidae</span> Family of mammals

Erinaceidae is a family in the order Eulipotyphla, consisting of the hedgehogs and moonrats. Until recently, it was assigned to the order Erinaceomorpha, which has been subsumed with the paraphyletic Soricomorpha into Eulipotyphla. Eulipotyphla has been shown to be monophyletic; Soricomorpha is paraphyletic because Soricidae shared a more recent common ancestor with Erinaceidae than with other soricomorphs.

<span class="mw-page-title-main">Gargano</span> Historical and geographical region of Italy

Gargano (Italian:[ɡarˈɡaːno], is a historical and geographical sub-region in the province of Foggia, Apulia, southeast Italy, consisting of a wide isolated mountain massif made of highland and several peaks and forming the backbone of the Gargano Promontory projecting into the Adriatic Sea, the "spur" on the Italian "boot".

<i>Myotragus</i> Extinct genus of mammals

Myotragus is an extinct genus of goat-antelope in the tribe Caprini which lived on the Balearic Islands of Mallorca and Menorca in the western Mediterranean until its extinction around 4,500 years ago. The fossil record of Myotragus on the Balearic Islands extends over 5 million years back to the early Pliocene on Mallorca, where it presumably arrived after the evaporation of the Mediterranean Sea during the Messinian Salinity Crisis.

<i>Percrocuta</i> Extinct genus of carnivores

Percrocuta is an extinct genus of hyena-like feliform carnivores. It lived in Europe, Asia, and Africa, during the Miocene epoch.

<span class="mw-page-title-main">Shrew gymnure</span> Species of mammal

The shrew gymnure, or shrew hedgehog, is a species of mammal in the family Erinaceidae and is the only extant species in the genus Neotetracus. It is found in China, Myanmar, and Vietnam.

<i>Podogymnura truei</i> Species of mammal

Podogymnura truei, also known as the Mindanao gymnure, Mindanao moonrat, or Mindanao wood shrew, is a mammal of the family Erinaceidae. It is endemic to the Mindanao islands of the Philippines. Erinaceidae is a family of small mammals that include the gymnures, also known as the silky furred moonrats, and the hedgehogs. Animals belonging to this family are significant because they are among the oldest known placental mammals that are alive. Gymnures are relatives of hedgehogs but lack the prickly spines. Four species are categorized in the genus Podogymnura: P. aureospinula, P. intermedia, P. minima, and P. truei. All share a close resemblance to the moonrat Echinosorex gymnura, which is commonly found on the Borneo, Sumatra, and the Malay Peninsulas.

<i>Tyto gigantea</i> Extinct species of bird

Tyto gigantea is an extinct barn owl from what is now Gargano, Italy, dating back to the late Miocene. From its remains, T. gigantea is suggested to have been as large as or larger than the Eurasian eagle-owl.

<i>Tyto robusta</i> Extinct species of bird

Tyto robusta was a prehistoric barn-owl. It lived at what is now Monte Gargano in Italy, and was an island throughout much of the Neogene when sea levels were higher. The owl's remains date back to the Miocene-Pliocene boundary 5.5 to 5 million years ago. The fossil bones are about 60% as long again as a modern barn owl, giving a total length of about 50–65 cm for T. robusta. This owl provides an interesting case study of evolution and insular gigantism.

<i>Prolagus</i> Extinct genus of mammals

Prolagus is an extinct genus of lagomorph. Over 20 species have been named, and the genus was abundant and widespread in Europe during the Neogene. However, by the end of the Middle Pleistocene, it was confined to a single species, the Sardinian pika, on the Corsica, Sardinia, and surrounding islands, where it survived into historical times. In North Africa and Western Asia, the genus is known from the Miocene and Pliocene. The scientific name may mean "before hares" or "primitive hares". Its taxonomy is disputed, with it either being considered a member of the family Ochotonidae, which includes living pikas, or the only member of the family Prolagidae.

<i>Hoplitomeryx</i> Extinct genus of deer

Hoplitomeryx is a genus of extinct deer-like ruminants which lived on the former Gargano Island during the Miocene and the Early Pliocene, now a peninsula on the east coast of South Italy. Hoplitomeryx, also known as "prongdeer", had five horns and sabre-like upper canines similar to a modern musk deer.

Galerix is a prehistoric genus of gymnures. Fossils of these hedgehog-like creatures are found in Europe, Africa, and Asia.

<i>Leithia</i> Extinct genus of giant dormice

Leithia is an extinct genus of giant dormice from the Pleistocene of the Mediterranean islands of Malta and Sicily. It is considered an example of island gigantism. Leithia melitensis is the largest known species of dormouse, living or extinct, being twice the size of any other known species.

<i>Rhagamys</i> Extinct rodent genus

Rhagamys is an extinct genus of rodents in the subfamily Murinae, the Old World mice and rats. The genus was established by the Swiss zoologist Charles Immanuel Forsyth Major to accommodate Rhagamys orthodon, which is the only species in the genus. It was endemic to the Mediterranean islands of Corsica and Sardinia, descending from Rhagapodemus, which had colonised the islands around 3.6 million years ago. Its closest living relatives are of the genus Apodemus, which includes the field and wood mice.

<i>Garganornis</i> Extinct genus of birds

Garganornis is an extinct genus of enormous flightless anatid waterfowl from the Late Miocene of Gargano, Italy. The genus contains one species, G. ballmanni, named by Meijer in 2014. Its enormous size is thought to have been an adaptation to living in exposed, open areas with no terrestrial predators, and as a deterrent to the indigenous aerial predators like the eagle Garganoaetus and the giant barn owl Tyto gigantea.
