Laño (Basque: Lañu) is a hamlet and concejo (a small administrative subdivision) in Condado de Treviño within the Treviño enclave; which is administratively part of the Spanish province of Burgos, but which is completely surrounded by the territory of the Basque country province of Álava. It is best known for the fossils of extinct vertebrates dating from around 70 million years before present which have been found there.

Palaeontology

The Paleontology Unit of the University of the Basque Country and other scientists have studied the fossil record at Laño. The fossils are from the late Cretaceous (late Campanian to lower Maastrichtian). It has been inferred that there was then a braided riverbed at the site, that the sea was nearby, and that the climate was tropical or sub-tropical.[1][2]

Taxa identified at Laño include:

Acynodon iberoccitanus, a species of crocodilian in genus Acynodon
Dortoka vasconica, a species of turtle in genus Dortoka in family Dortokidae in sub-order Pleurodira
Herensugea caristiorum, a species of snake in genus Herensugea in family Madtsoiidae
Lainodon orueetxebarriai, a species of placental mammal in genus Lainodon in family Zhelestidae
Lirainosaurus astibiae, a species of sauropod dinosaur in genus Lirainosaurus
Madtsoia laurasiae, a species of snake in genus Madtsoia
