Belemnites in Mythology: From Thunderstorms to Fertility Symbols.

Belemnites are a group of now extinct marine coleoids cephalopods that lived during the Mesozoic (240 Mya – 65 Mya). Unlike modern squids, belemnites had a hard internal skeleon made of calcium carbonate called a rostrum. Like many fossil groups, belemnites have been associated with numerous myths and legends in folklore. Belemnites take their name from the Greek word belemnon meaning dart or jave ...[Read More]

What’s my age again? Comparing dating methods in loess

As you have learned from our previous posts, loess is a widespread terrestrial sediment, known to be an important archive for the changes of past environmental and climatic conditions. In order to use loess as a proxy, we first need to investigate the age of the sediments. In loess, different dating methods can be used, such as luminescence dating, radiocarbon dating, magnetic stratigraphy, and or ...[Read More]
