Hippopotamus Fossil

In a recent study published on November 22, 2023, in the open-access journal PLOS ONE, led by Beniamino Mecozzi from the Sapienza University of Rome and his colleagues, a profound revelation about the history of modern hippos in Europe has emerged. This groundbreaking research unravels the complexities surrounding the age and origin of a crucial fossil, shedding light on a chapter of Earth’s history dating back to the Middle Pleistocene.

Modern hippos, scientifically known as Hippopotamus amphibius, have their roots in Africa during the Quaternary period when these majestic creatures roamed Europe. However, the precise details of how and when this species made its way into Europe have remained a subject of intense debate among experts. Mecozzi and his team aimed to provide fresh insights into this enigma by scrutinizing a fossilized hippo skull discovered in the Tor di Quinto region of Rome.

The Tor di Quinto Skull’s Significance

The Tor di Quinto skull, currently residing in the Earth Science University Museum at Sapienza University of Rome, stands as one of the most complete Pleistocene European hippo specimens known to science. Nonetheless, its true significance had been shrouded in uncertainty, primarily due to questions regarding its age and the precise location of its excavation.

In 2021, following a meticulous restoration process, researchers had the opportunity to analyze the sediment composition within the skull’s cavities. This analysis provided a crucial clue, as it indicated a geological age for the skull, ranging from 560,000 to 460,000 years old, aligning it with the local Valle Guilia Formation. Additionally, the examination of cranial and dental features conclusively confirmed the identity of the skull as belonging to the modern species Hippopotamus amphibius.

Unearthing Hippo History in Europe

This groundbreaking research has now firmly established the Tor di Quinto skull as the oldest known fossil of the modern hippo species in Europe. The implications of this discovery are far-reaching, as it sheds unprecedented light on the history of hippos on the European continent. It provides substantial support for the hypothesis of an early dispersion of hippos during the Middle Pleistocene, significantly enriching our understanding of the deep-rooted history of these magnificent creatures.

It’s essential to note that hippos hold immense ecological importance in both contemporary and ancient ecosystems, serving as vital indicators of past climate and environmental conditions.

In the words of the authors themselves: “Restoring the mammal skeletons exposed at the University Museum of Earth Science, Terra, Sapienza University of Rome offers new data for old fossils. The multidisciplinary study of the skull from Cava Montanari (Roma) redefines the first dispersal of Hippopotamus amphibius in Europe.”
