Plant fossils from White Island

Fossils and plant phylogeny.

Developing a detailed estimate of plant phylogeny is the key first step toward a more sophisticated and particularized understanding of plant evolution. At many levels in the hierarchy of plant life, it will be impossible to develop an adequate understanding of plant phylogeny without taking into account the additional diversity provided by fossil plants. This is especially the case for relativ...

Plant Fossils in the Clarno Formation, Oregon

The Clarno formation was originally described by Merriam (1901) from outcrops at Mitchell and Clarno's Ferry, Oregon. Since that time the formation has been found to be very widely distributed throughout central Oregon (Wilkinson, 1959). It is composed of an unknown thickness of volcanic rocks and interfingering terrestrial sediments which contain a newly discovered vertebrate fauna and an abun...

A Quantitative Reassessment based on Plant Fossils

Notes on the Ordovician Fossils from Bear Island Collected Du Ring the Swedish Expeditions

D uring his Arctic Expedition in the summer of 1898 A. G. NATHORST 1 succeeded in finding fossils in a limestone of the socalled Heclahook-system of Bear Island, the small inlet lying iso1ated between Norway and Spitzbergen, at about 7 41/2 o N. L. (see map p. 91 ). This Heclahook-system consists of a series of limestone, dolomite, quartzitic sandstone and shale, folded and generally very much ...

Compound trace fossils formed by plant and animal interactions: Quaternary of northern New Zealand and Sapelo Island, Georgia (USA)

Quaternary coastal-terrestrial deposits from Aupouri and Karikari Peninsulas, northern North Island (New Zealand), and from Sapelo Island, Georgia (USA), reveal sedimentary structures produced by plant roots that provided habitats suitable for root-sucking, deposit-feeding, burrowing, brooding and other terrestrial invertebrate activities. The structures are typically large (<1 to >2 m in lengt...
