Ursus dolinensis is an extinct mammalian carnivore species of the Ursidae family. Its fossilized remains were unearthed from the lowest layers of the stratigraphic sequence at the archaeological and paleontological site of Gran Dolina, that is a part of the Atapuerca Mountains complex in the Burgos province, northern Spain. The species was described by Nuria Garcia and Juan Luis Arsuaga in a 2001 publication. Skeletal fossils, mainly cranial fragments were recovered from the sediment units TD 3 and in particular TD 4 . Presence in these layers suggests a chronology in between 900,000 and 780,000 years ago, which falls into the Calabrian stage of the early Pleistocene.
