Early Jurassic
Estuarine Series
Scarborough, Yorkshire, England, U.K.
Except in isolated parts of China, the gingko became extinct during the Tertiary period. However, it has experienced a remarkable revival since its reintroduction from China during modern times. This tree has thrived especially in America, where it has become a common "street" tree, and its hardiness raises questions about why it became extinct in Europe in the first place. Cellular structure is clearly apparent in the leaves pictured here, and their very black color suggests that residues of the original cellular carbon are present.
