Humans and saber-toothed cats coexisted 300,000 year ago in central Europe, a new fossil study suggests.
Scientists excavating at the Schoningen open-cast coal mine in north-central Germany have discovered the remains of a saber-toothed cat preserved in a layer some 300,000 years old - the same stratum in which wooden spears were found.
The finding indicates that early humans also inhabited the area, which at that time was the bank of a shallow lake.
The discovery sheds new light on the relationship between early humans and beasts of prey, researchers said.
It is highly likely that humans were confronted by saber-toothed cats at the Schoningen lakeside.
In that case, all the human could do was grab his up to 2.3m long spear and defend himself, they said.
In this context, the Schoningen spears must be regarded as weapons for defence as well as hunting - a vital tool for human survival in Europe 300,000 years ago.
Officials from the Lower Saxony heritage authority and archaeologists from the Universities of Tubingen and Leiden uncovered a first tooth of a young adult homotherium latidens in October 2012.
Measuring more than a metre at the shoulder and weighing some 200kg, the saber-tooth was no pussycat. It had razor-sharp claws and deadly jaws with upper-jaw canines more than 10cm long.
The find shows that the saber-toothed cat died out later in central Europe than previously believed.
Along with the sensational wooden spears, the same level has yielded bones and stone tools indicating that early humans - probably homo heidelbergenis - hunted horses and camped along a 100m stretch of the lakeside.
The finding demonstrates that a long time before anatomically modern humans, homo sapiens sapiens reached Europe some 40,000 years ago, early man was able to defend himself against highly dangerous animals with his weapon technology.
