Cast Glass Ammonites"Ammonites have always held a sense of wonder and intrigue. Not only are they aesthetically stunning and technologically impressive but their fossils have survived to tell us stories that are millions of years old, so naturally I just had to cast some of these beautiful treasures in glass. The fossilised for casting is said to be from a White Spine Ammonite Peisphinctes virguloides that was living in Madagascar 160 million years ago," Rebecca Heap
