Ancient saber-toothed cat skull discovery in Germany

“Homotherium” is an extinct genus of machairodontine saber-toothed cats, often termed “scimitar-toothed cats”, that ranged from North America, South America, Eurasia, and Africa during the Pliocene and Pleistocene epochs.

It first became extinct in Africa some 1.5 million years ago. In Eurasia it survived until about 30,000 years ago. In South America it is only known from a few remains in the northern region, from the mid-Pleistocene. The most recent remains of Homotherium date to 28,000 years BP.

“Homotherium” reached 1.1 m at the shoulder and weighed an estimated 150 [kilogram] – and was therefore about the size of a male African lion. Compared to some other machairodonts, like “Smilodon” or “Megantereon”, “Homotherium” had shorter upper canines, but they were flat, serrated and longer than those of any living cat. Incisors and lower canines formed a powerful puncturing and gripping device. Among living cats, only the tiger has such large incisors, which aid in lifting and carrying prey. The molars of “Homotherium” were rather weak and not adapted for bone crushing. The skull was longer than in “Smilodon” and had a well-developed crest, where muscles were attached to power the lower jaw. This jaw had down-turned forward flanges to protect the scimitars. Its large canine teeth were crenulated and designed for slashing rather than purely stabbing.

It had the general appearance of a cat, but some of its physical characteristics are rather unusual for a large cat. The limb proportions of “Homotherium” gave it a hyena-like appearance. The forelegs were elongated, while the hind quarters were rather squat with feet perhaps partially plantigrade, causing the back to slope towards the short tail. Features of the hind limbs indicate that this cat was moderately capable of leaping. The pelvic region, including the sacral vertebrae, was bear-like, as was the short tail composed of 13 vertebrae—about half the number of long-tailed cats.

Skull of saber-toothed cat found almost complete

Third individual saber-toothed cat was discovered in Schöningen

April 12, 2017

Summary: An excavation team found the remains of a saber-toothed cat at the archeological site in Schöningen. An examination of the skull fragments revealed the animal to be a representative of the European saber-toothed cat, Homotherium latidens. The recent discovery constitutes the third example of this large predatory cat from Schöningen.

Led by scientists of the Senckenberg Research Institute and the University of Tübingen, the excavation team found the remains of a saber-toothed cat at the archeological site in Schöningen. An examination of the skull fragments at the Dutch University of Leiden revealed the animal to be a representative of the European saber-toothed cat, Homotherium latidens. The recent discovery constitutes the third example of this large predatory cat from Schöningen.

Long claws, razor-sharp, curved canine teeth and the size of a fully grown lion: the saber-toothed cat (Homotherium latidens) was a competitor as well as a dangerous predator that even posed a risk to the humans of its time. “In the course of our excavation in May 2015, we came across conspicuous bone fragments,” explains Dr. Jordi Serangeli, a scientist at the University of Tübingen and the excavation leader at the approximately 300,000-year-old archeological site, and he continues, “In total, there are three individuals of Homotherium present in these relatively young sediment layers.

Until the first discovery of a saber-toothed cat in 2012 at the Schöningen excavation site in Lower Saxony it had been assumed that the large cats were already extinct about 200,000 years earlier, i.e., around 500,000 years ago. “Our findings show that 300,000 years ago, the saber-toothed cats were not as rare as previously thought,” adds Serangeli.

During a restoration in 2016, André Ramcharan and Ivo Verheijen at the University of Leiden were able to reassemble the eleven bone fragments into an almost complete neurocranium. “We then compared the reconstructed skull with recent and already extinct species of large carnivores and were thus able to demonstrate that the remains represented the head of a European saber-toothed cat,” explains Professor Dr. Thijs van Kolfschoten of the University of Leiden.

The third saber-toothed cat specimen that was discovered offers a great potential: thanks to the excellent level of preservation at the Schöningen dig, the interior of the skull reflects the shape and structure of the Homotherium brain. By examining the detailed brain structures, the team of scientists hopes to gain insights into the visual and hearing abilities as well as the feeding habits of the large cats. “The third Homotherium from Schöningen is invaluable for our understanding of the European saber-toothed cat,” summarizes Professor Nicholas Conard of the Senckenberg Centre for Human Evolution and Palaeoenvironment and head of the Institute for Early Prehistory and Quaternary Ecology at the University of Tübingen.

In the near future the international team from the Schöningen project intends to publish the results of its interdisciplinary studies regarding the three saber-toothed cats discovered to date. “Moreover, we expect that future digs will produce additional Homotherium finds,” offers Serangeli as a preview.

The dig in Schöningen keeps a team of ten members employed full-time — and during the main excavation season, the team is joined by five to ten students, who support the scientific excavation. Worldwide, about 50 scientists from 30 institutions and a wide variety of disciplines are involved in researching the discoveries from Schöningen. The dig is financed by the State of Lower Saxony.

The spectacular new discovery is put on display for the public at the palaeon in Schöningen as part of the special exhibition “The Ice Age Huntress.” Thanks to the close cooperation between Senckenberg, the international partners and the der palaeon GmbH, it is possible to make spectacular scientific findings available to the public in a timely manner.
