New finds of giant raptorial sperm whale teeth (Cetacea, Physeteroidea) from the Westerschelde Estuary (province of Zeeland, the Netherlands)

Two large sperm whale teeth were found offshore from Breskens in the Westerschelde estuary. Comparison shows they share features with the teeth of the stem physteroid Zygophyseter, described from the Late Miocene of southern Italy. Both teeth are however significantly larger than the teeth of the Zygophyseter type material, yet still somewhat smaller than the teeth of the giant raptorial sperm whale Livyatan melvillei, and confirm the presence of so far undescribed giant macroraptorial sperm whales in the Late Miocene of The Netherlands.
