Hauterivian
Definition
- The Hauterivian is, in the geologic timescale, an age in the Early Cretaceous Epoch or a stage in the Lower Cretaceous Series. It spans the time between 132.6 ± 2 Ma and 125.77 (million years ago). The Hauterivian is preceded by the Valanginian and succeeded by the Barremian. It is named after the Swiss town of Hauterive at the shore of Lake Neuchâtel. Some palaeoclimatological studies indicate that a brief ice age, known as the Hauterivian cold snap, occurred during this age. The Hauterivian cold snap appears to be associated with permafrost at high elevations and large ice sheets that potentially stretched as far south as the modern Iberian Peninsula, based on the existence of Hauterivian ice-rafted dropstones in Iberia. Cold conditions are also known to have existed in the Southern Hemisphere during the same time period, based on records from Australia. (Adapted from: https://en.wikipedia.org/wiki/Hauterivian)
