It’s clearly #FossilFriday at NfN, as the Trilobites are joined by Foraminifera!
A few words from our Senior Curator of Micropalaeontology, Giles Miller, about the Larger Benthic Forams in this collection:
One of my curatorial predecessors Randolf Kirkpatrick (1863-1950) thought that larger benthic foraminifera (LBFs) were so important that he published a theory that they were vital to the formation of all rocks on earth. Our collection of LBFs has received relatively little attention over the 20 years I have been at the Museum, but recently it has been the most viewed part of the microfossil collection.
Traditionally LBFs have been difficult to study but new techniques, particularly CT scanning, are changing this perception. This post “The importance of being the largest microfossils” tells the story of Kirkpatrick and explains how the collection is currently being used for studies in stratigraphy, oil exploration, past climates and biodiversity hot spots.
Larger benthic foraminifera (LBF)
Larger benthic foraminifera are classified as microfossils because they were produced by a single celled organism, but they can reach a size of several centimetres. Their study is difficult because it usually relies on destructive techniques such as thin sectioning to make precise identifications.
My first line manager at the Museum Richard Hodgkinson was an expert at producing these thin sections. He described the technique of cutting the specimens exactly through the centre as an art rather than science.
Sadly there are very few people in the world skilled enough to make these sections, but thankfully the Museum collection is packed with LBF thin sections available for study.
Thank-you for helping to make this possible, by making all of the data in this collection available to research, along with the images of the specimens themselves.
