Radiolarian Micropalaeontology: Analysing Radiolarian Microfossil Data

Description

Professor Simon Haslett discusses analysing radiolarian microfossil data. Radiolaria are marine single-celled organisms that possess a silica shell and are preserved in the fossil record. Radiolarian data can be analysed by individual species plots/graphs, or through numerical and statistical analysis of assemblage datasets. Such data can be used in stratigraphy to date layers of rock and sediment through geological time, and also to reconstruct past environments and establish palaeoclimate history.

Radiolarian micropalaeontology: examining radiolaria under the microscope

Description

Professor Simon Haslett discusses examining radiolarian microfossils under the microscope. Radiolaria are marine single-celled organisms that possess a silica shell and are preserved in the fossil record. They are commonly examined using transmitted light microscopy and scanning electron microscopy. Radiolaria can be used in stratigraphy to date layers of rock and sediment through geological time, and also to reconstruct past environments and establish palaeoclimate history.

Radiolarian micropalaeontology: extracting radiolaria from sediment

Description

Professor Simon Haslett discusses extracting radiolarian microfossils from rocks and sediments. Radiolaria are marine single-celled organisms that possess a silica shell and are preserved in the fossil record. They can be collected from sediment accumulating on the sea-floor and retrieved through coring and extracted through sieving and chemical treatments. Radiolaria can be used in stratigraphy to date layers of rock and sediment through geological time, and also to reconstruct past environments and establish palaeoclimate history.

Radiolarian micropalaeontology: collecting radiolaria

Description

Professor Simon Haslett discusses collecting radiolarian microfossils. Radiolaria are marine single-celled organisms that possess a silica shell and are preserved in the fossil record. They can be collected from sediment accumulating on the sea-floor and retrieved through coring, such as by the Deep Sea Drilling Project (DSDP), the Ocean Drilling Program (ODP) and the Integrated Ocean Drilling Program (IODP). Radiolaria can be used in stratigraphy to date layers of rock and sediment through geological time, and also to reconstruct past environments and establish palaeoclimate history.
