A new transfer technique to extract and process thin and fragmented fossil cuticle using polyester overlays

Extraction and chemical processing of fragmented cuticles from fossil leaves are facilitated by a new non-destructive technique. Transfer of fossil cuticle onto polyester overlays renders whole-leaf maceration unnecessary. This technique is completely safe and extremely easy to apply for the preparation of fragile and fragmented cuticles, while preserving the fossil specimen and reducing chemical processing time.
