Torralba and Ambrona (archaeological site)
Torralba and Ambrona are two paleontological and archaeological sites in the province of Soria, Castile and León, Spain, about 3 kilometers apart. They contain Lower to Middle Paleolithic evidence, including Acheulean stone tools, and fossil remains of large mammals that date to around 350,000 years ago. Ambrona belongs to the Miño de Medinaceli area and Torralba del Moral to Medinaceli. The finds come from several fossil-rich layers and show repeated human presence, likely as hunting stations or, more probably, as places where people scavenged and processed carcasses.
Both sites are best known for the large numbers of elephant remains. Each site has evidence for around fifty individual Straight-tusked elephants, along with horses, aurochs and deer. The bone concentrations resemble what many describe as an “elephants’ graveyard,” a term that is debated because it can oversimplify how the bones accumulated.
Excavation history and discoveries
- The first excavations were led by the Marquis of Cerralbo between 1909 and 1914. He opened large areas at Torralba and Ambrona, uncovering hundreds of elephant bones and many lithic tools, and helping bring international attention to the sites.
- In the 1960s and again in the early 1980s, American archaeologist Francis Clark Howell conducted major campaigns with a large international team. These digs used modern methods, documented stratigraphy carefully, and raised important questions about how people used the landscape—whether they hunted or mainly scavenged—and about fire use at the sites.
- From 1990 to 2000, Manuel Santonja and Alfredo Pérez-González directed campaigns that focused on precise geology and detailed stratigraphy, mainly at Ambrona. They described several lithic and fossil layers (AS1–AS7) and reconstructed the changing environments through time, from fluvial-lacustrine settings to more open landscapes. They dated the deposits using methods such as electron spin resonance and uranium-thorium dating and studied paleomagnetism to place the sites in the Brunhes normal polarity period, about 350,000 years ago.
What was found
- Stone tools: The lithic assemblage is rich but relatively sparse compared with the excavated volumes. It consists of late or middle Acheulean types, including hand axes, cleavers, scrapers, denticulates and other implements, made from flint, quartzite, limestone and quartz. Much of the lithic material shows signs of transport or secondary working rather than in-situ manufacture.
- Animal remains: Large mammal bones are abundant, with elephants the most represented. In Ambrona, the upper levels show more horse remains. The bones are often fragmentary and show grazing, transport by water, and occasional but debated signs of human modification.
- Human behavior: The major question has been whether their interactions with the bones reflect active hunting or opportunistic scavenging. Some fractures and marks have been interpreted as evidence of bone tool use or processing, but this interpretation remains controversial. Some researchers propose rudimentary bone tools or hammerstones made from ivory tips, while others see the evidence as primarily natural accumulation and carcass processing.
- Environment and climate: Pollen, diatoms and ostracods indicate a temperate, somewhat humid climate with fluvial and lacustrine environments. Vegetation would have included pines in some phases, with alder, willow, elm and juniper at other times, and a landscape that alternated between open meadows and forested areas.
Legacy and present-day access
- The finds from these campaigns are distributed mainly across major Spanish museums, including the Museo Nacional de Ciencias Naturales, the Museo Arqueológico Nacional, the Museo Numantino de Soria, and the in-situ Ambrona Museum.
- In 1995, the Torralba-Ambrona complex was designated as a Bien de Interés Cultural in the category of archaeological zone. It has also been recognized as a geological “geosite” of international relevance (VP-07 and VP-07b) for its vertebrate Pliocene–Pleistocene records.
- An on-site museum at Ambrona, opened in 1963 and created by Emilio Aguirre, preserves and presents material as it was found. It was one of Spain’s first museums built directly on a major archaeological site.
Torralba and Ambrona thus offer a rare window into early human activity in western Europe, the behavior of Pleistocene megafauna near water, and the long history of archaeological science in documenting and interpreting ancient landscapes.
