A new terrestrial Cretaceous-Paleogene site in New Zealand-turnover in macroflora confirmed by palynology
(2009) In Cretaceous Research 30(4). p.917-938- Abstract
- A fluvial sequence near Cave Stream (north of Castle Hill Village, central Canterbury), New Zealand, contains organically-preserved plant macrofossils (cuticles). The almost ubiquitous presence of Araucariaceae macrofossils in the lower part of the section and their stratigraphic disappearance roughly coincident with the appearance of the angiosperm leaf Dryandra comptoniaefolia and conifer taxa only known elsewhere from sediments of Paleogene age, indicates that the section spans the Cretaceous-Paleogene (K-T) boundary. This was subsequently confirmed by a palynological study that demonstrated the disappearance of Late Cretaceous index species within the investigated exposure. The sequence supports the pattern recognized elsewhere in New... (More)

This was subsequently confirmed by a palynological study that demonstrated the disappearance of Late Cretaceous index species within the investigated exposure. The sequence supports the pattern recognized elsewhere in New Zealand where Araucariaceae macrofossils either disappear or become very rare in end-Cretaceous and the leaf Dryandra comptoniaefolia is an important component in the early Cenozoic. The Cave Stream K-T boundary is one of the very few in the world with organically-preserved plant macrofossils and confirms the dramatic turnover in macroflora, which is known from North America.
