A Triassic Lagerstatte from eastern North America

Article Abstract:

The Lagerstatte present on the Virginia-North Carolina border is composed of shales that contain many insect and plant fossils from the late Triassic era. The aquatic heteropterans and the auchenorrhyncans are the most abundant fossil insects. The shales also contain fossils of a nepomorph Heteroptera, a Psychodoidea and tetrapods, and a shark's tooth. The fossil of Crosaphis shows that the insect is a dipteran. Most of the plant fossils are of ferns, cycadeoids, and conifers.

Mammal bones in Dominican amber

Article Abstract:

The discovery of mammalian bones preserved in amber on the Greater Antilles, West Indies, provides the first fossil evidence of larger vertebrates on the island. Several partially articulated ribs and six vertebrae are in the amber piece, allowing for an identification of the sample as from a Nesophontes-sized, small insectivore. The oldest possible date for the amber is in the Late Oligocene or Early Miocene.

New light shed on the oldest insect

Article Abstract:

Specimens in chert from Rhynie and Scotland's Old Red Sandstone are among the few fossils that provide insight into the earliest stages of insect evolution. However, in this study it is showed that a fragmentary fossil from Rhynie, is not only the earliest true insect but may be relatively derived within basal Ectognatha.
