Description

Laser-stimulated Fluorescence images of the fossils used in Barlow et al. 2021 - "Laser-Stimulated Fluorescence reveals unseen details in fossils from the Upper Jurassic Solnhofen Limestones". The decapods fluoresce brightly due to autofluorescent compounds in their exoskeleton which allows for the whole animal to be seen. Ammonites possess a phosphatised siphuncle in some specimens allowing for it to picked out from the surrounding shell. Fish are mostly articulate and some specimens have fluorescing gut contents due to the concentration of phosphate in the stomach. Original photos taken by myself are provided below. Pterosaurs show differential preservation with preserved bone and skeletal imprints. The crocodyliform shows soft tissues around the body, especially in the caudal region. Original photos of specimens studied within this paper taken by MP and TK are available below.

Steps to reproduce

Using the methods provided in our paper, the method is simple to reproduce and reveals exciting results on Lagerst├Ątten, especially where soft tissues that are invisible under white light, can be observed through fluorescence.
