It was found on October 21, 1907, at a depth of 24 m in the Grafenrain sand pit, resting in fluvial sediments named the “Mauer sands” (1).These Mauer sands, including sands and gravels, were deposited by the Neckar River in its former course and are subdivided into two distinct units: the “lower sands” and the “upper sands,” separated from each other by a clay/silt layer, the “Lettenbank” (Fig. The mandible of Both sand units are renowned for their rich early Middle Pleistocene mammal fauna that clearly indicate warm climate conditions (2) attributed to two distinct Middle Pleistocene interglacial stages.Today, Heidelberg Cement priced a Eurobond issue (ISIN XS1529515584) under its €10 billion EMTN programme with an issuance volume of €1 billion and a maturity date of 7 February 2025.
Here we show that two independent techniques, the combined electron spin resonance/U-series method used with mammal teeth and infrared radiofluorescence applied to sand grains, date the type-site of at Mauer to 609 ± 40 ka.
This result demonstrates that the mandible is the oldest hominin fossil reported to date from central and northern Europe and raises questions concerning the phyletic relationship of ” fossils from Trinil in Java, the Mauer jaw is one of the classic finds of paleoanthropology.
Moody’s is the second rating agency to assign an Investment Grade rating to Heidelberg Cement after S&P Global Ratings.
, was found in 1907 in fluvial sands deposited by the Neckar River 10 km southeast of Heidelberg, Germany.
The fossil is an important key to understanding early human occupation of Europe north of the Alps.
