Scientists from the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) have published a paper in the International Journal of Paleopathology that describes the first case of a congenital pathology in vertebrae of a cave bear (Ursus spelaeus). The findings were based on a specimen recovered in the 2014 excavation campaign in the archaeological and paleontological site of Cueva de Guantes, in Santibáñez de la Peña (Palencia).
