Biosystems, 1991
The approximately 300 million years that make up Paleozoic time saw the evolution of eight of the fifteen recognized suborders of Foraminifera. Of the suborders present in the Paleozoic, seven are morphologically relatively simple, slowly evolving, and continued into Mesozoic and Cenozoic times to become the ancestoral lineages from which evolved ...

Paleozoic paleogeographies should be consistent with all available, reliable data. However, comparison of three different Devonian paleogeographies that are based largely or wholly on the data of remanent magnetism show them to be inconsistent in many regards.

Seeds in a conifer cone from the Lower Permian of west Texas contain embryo tissue. These are the oldest plant embryos on record. Their development prior to seed dispersal shows that the sequence of embryo growth typical of most modern seed plants had evolved before the end of the Paleozoic Era.

An unusually well-preserved Ordovician fossil from Czechoslovakia shows that the enigmatic paired structures once thought to be outgrowths of the operculum of Hyolithes are really independent structures lying between the operculum and the aperture of the shell.

A Silurian, and perhaps Devonian, limestone belt in northern West Pakistan contains the first Paleozoic reefs found on the Indo-Pakistan subcontinent. The belt contains a rich fauna entirely new to Pakistan. Its presence indicates that this area was inundated in Silurian and Devonian times by seas bordered by reefs or containing reef platforms.

Notes for a Short Course: Studies in Geology, 1980
In accordance with the stated purpose of this short course to bring non-specialists up to date on advances in echinoderm paleontology, these notes build on what may be considered common knowledge of the Paleozoic Asterozoa. They are intended to be additions to information available in most paleontology textbooks and to update and comment on information

Abstract Several significant sections of Paleozoic and Mesozoic rocks occur in close proximity to one another at the foot of the Front Range west of Denver. The Paleozoic section on the east flank of the central Front Range is well exposed in Red Rocks Park.
