Are there miniature elephants

These glacials are colloquially known as ice ages, and many existed during the relatively short duration of this period.

The fossil remains were discovered between and In total, the find consisted of bones of individual animals, making Spinagallo one of the richest Pleistocene sites in the Mediterranean. Bones like these had been seen before, yet at the same time there was something different about them and further studies were done by a number of researchers in the succeeding years.

The Spinagallo oddities were dwarf elephants, somewhat of a paradox to those who know and love the giants of Africa and South Asia today. However, the idea of a tiny elephant is not as strange as it sounds, neither is it a very new idea. The Greek islands seem to be full of them, with remains ranging from Cyprus and Naxos to Crete. The majority of these elephants belonged to a widespread genus called Palaeoloxodon, a close relative of Asian elephants that varied dramatically in terms of size.

This animal roamed Eurasia during the Pleistocene during warmer episodes, with the European Palaeoloxodon antiquus being the best known. This species was also one of the larger elephants of the time, growing as tall as 4.

Fossils of the European Palaeoloxodon and its neighbors have been known for centuries, with the Ancient Greeks regarding the bones as those of fallen giants. These huge creatures are thought to have roamed the Italian peninsula in large numbers and it is one of these that gave rise to the island dwarfs.

The new paper suggests that Sicilian Palaeoloxodon falconeri is in fact, the smallest advanced elephant ever discovered. All the animals from the cave, including the endemic rodent fauna, date back to , years ago, long before any humans arrived in Europe. In terms of body form and physiology, this species is perhaps the most novel, with dwarfing having brought on changes unseen in other species. The new research paper points out that these elephants have features similar to a baby mainlander.

This also gives them a very large brain in comparison to other elephants, especially when compared to mainland Palaeoloxodon. Studies of the brain mass also point out that the dwarfs probably had good cognitive abilities. This was a surprise, considering that intelligence itself is a relative concept yet the Sicilian dwarfs seem to have been ahead of the pack.

Not only are the skulls somewhat rounder and shorter but even the bodies of the Sicilian elephants were markedly different from their ancestral stock.

The skeleton of a dwarf elephant found on the island of Sicily, where the creatures underwent a remarkably rapid reduction in size.

Ancient elephants that colonized the island of Sicily no earlier than , years ago shrank drastically in size generation by generation, probably owing to food scarcity. Download references.

In the 17th century, the Sultan of Sulu was given of collection of captive elephants, and these elephants were subsequently released into the Borneo jungle.

Comparison of DNA with other elephant subspecies has found that Borneo elephants are derived from Sundaic stock and became an isolated, genetically divergent population , years ago. The primary threat to these elephants is habitat loss. As their forests become fragmented due to human encroachment, populations are no longer able to travel along their traditional migration routes, and subpopulations are no longer able to breed to maintain genetic diversity.

Pygmy elephants lose their forest homes as the ever-expanding human population builds roadways and infrastructure and converts their habitat for agriculture, palm oil plantations and logging. The World Wildlife Fund has tracked these elephants in order to identify and maintain crucial forests and elephant corridors. Header Credit: Gavin Lautenbach. See Elephants on These Nature Safaris.

We've only had ancient DNA from German specimens. This is largely due to the environments in which the fossils were preserved, with the heat and humidity making it exceedingly difficult for any DNA to survive. The team were able to extract and sequence DNA from the petrous bone, a small and very dense bone found in the base of the skull, and one that is renowned for preserving ancient DNA.

The results have shown that the straight-tusked elephant lineage that led to the tiny elephants on Sicily actually split away from the German elephants around , years ago, even though these miniature elephants are only thought to have been isolated on Sicily within the last , years. This is intriguing because it suggests that in the gap between these dates, there was something interesting going on with the populations of these giant herbivores within continental Europe, perhaps a divide between those living in the north and those in the south.

The island of Sicily sits in the Mediterranean Sea just off the toe of Italy. While today the wildlife that lives on the island is much like that of the mainland, in the past it used to be home to a range of miniature animals. One of these was truly tiny, reaching just a metre in height and likely weighing around kg, they were about the same size as a Shetland pony. After this tiny species went extinct, a second miniature elephant evolved, albeit slightly bigger than this.

Fossils found in Puntali cave on Sicily reveal that this elephant stood around two metres tall and weighed around 1,kg. It is thought that both these miniature elephants evolved when the giant straight-tusked relatives reached Sicily when sea levels were up to metres lower than they are today, and then became trapped there after sea levels rose again. But how and when these giants colonised the island is still not fully understood.
