Subdivision of the Cretaceous system
according to the ICS, as of 2017.[1]

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 132.9 ± 2 Ma and 129.4 ± 1.5 Ma (million years ago). The Hauterivian is preceded by the Valanginian and succeeded by the Barremian.[2]

Stratigraphic definitions


The Hauterivian was introduced in scientific literature by Swiss geologist Eugène Renevier in 1873. It is named after the Swiss town of Hauterive at the shore of Lake Neuchâtel.


The base of the Hauterivian is defined as the place in the stratigraphic column where the ammonite genus Acanthodiscus first appears. A reference profile for the base (a GSSP) had in 2009 not yet been established. The top of the Hauterivian (the base of the Barremian) is at the first appearance of ammonite species Spitidiscus hugii.


In the ammonite biostratigraphy of the Tethys domain, the Hauterivian contains seven ammonite biozones:



  • zone of Pseudothurmannia ohmi

  • zone of Balearites balearis

  • zone of Plesiospitidiscus ligatus

  • zone of Subsaynella sayni

  • zone of Lyticoceras nodosoplicatus

  • zone of Crioceratites loryi

  • zone of Acanthodiscus radiatus

Zucchini (courgette) A striped and a uniform color zucchini Genus Cucurbita Species Cucurbita pepo Origin 19th century northern Italy The zucchini ( / z uː ˈ k iː n i / , American English) or courgette ( / k ʊər ˈ ʒ ɛ t / , British English) is a summer squash which can reach nearly 1 metre (100 cm; 39 in) in length, but is usually harvested when still immature at about 15 to 25 cm (6 to 10 in). [1] A zucchini is a thin-skinned cultivar of what in Britain and Ireland is referred to as a marrow. [2] [3] In South Africa, a zucchini is known as a baby marrow. Along with certain other squashes and pumpkins, the zucchini belongs to the species Cucurbita pepo . It can be dark or light green. A related hybrid, the golden zucchini, is a deep yellow or orange color. [4] In a culinary context, the zucchini is treated as a vegetable; it is usually cooked and presented as a savory dish o
