The oldest amber recovered dates to the Upper Carboniferous period (320 million years ago). Its chemical composition makes it difficult to match the amber to its producers - it is most similar to the resins produced by flowering plants, which did not evolve until the Jurassic, around 180 million years ago. Amber becomes abundant soon afterwards, in the Early Cretaceous, 150 million years ago, when it is found in association with insects.

Stone Swallow Barbaud, Belgium In ancient China, this stone was thought to be a swallow turned into fossil in the cave, and was called Stone Swallow. It sure is a fossil, but it is not a swallow. It is the fossil of a brachiopod called Spirifer, which flourished in Upper Devonian. This creature has beautiful form that looks like a bird with its wings spread. Spirifer is an ancestor of today’s “living fossil” species such as Lingula
