Graptolite Paleobiology
The graptolites constitute one of the geologically most useful taxonomic groups of fossils for dating rock successions, understanding paleobiogeography and reconstructing plate tectonic configurations in the Lower Palaeozoic. Graptolites were largely planktic, marine organisms, and as one of the first groups that explored the expanses of the world’s oceans are vital for understanding Palaeozoic ecology. They are the best and often the only fossil group for dating Lower Palaeozoic rock successions precisely. Thousands of taxa have been described from all over the planet and are used for a wide variety of geological and palaeontological (biological) research topics. The recent recognition of...
A Monograph of British Graptolites
Originally published between 1901 and 1918, and reissued here in two volumes, this monograph is notable for its accurate illustrations.
Graptolites
Graptolites lived in the earth's oceans from 540 million years ago to 320 million years ago, when they became extinct. For most of that time they dominated the upper layers of the ocean in tropical regions as the earth's first large zooplankton. They varied from a few millimetres in length to more than a metre; they lived by the countless billion, and their skeletons are preserved today in vast numbers in varied strata in every continent except Antarctica. Because of their diversity, they are a powerful correlative tool: units of time of much less than a million years are identifiable, and within individual rock sequences evolutionary changes can be studied, which makes them of prime importa...

Darriwilian to Katian (Ordovician) Graptolites from Northwest China
Darriwilian to Sandbian (Ordovician) Graptolites from Northwest China analyzes the significance of these exquisite, mostly pyritic, graptolites of the middle to late Ordovician period from North China and Tarim, China—locations that have developed the world’s most complete successions of strata and fossil records. The book provides the first systematic account of the renowned graptolite faunas, with over 100 species belonging to 45 genera and 15 families preserved in black shale and limestone, also presenting a comprehensive accounting of the graptolites during the critical transition from the middle to late Ordovician period with important data on new morphologies, the latest convention...
