- Description: Continental ecosystems of the middle Permian Period (273–259 million years ago) are poorly understood. In South Africa, the vertebrate fossil record is well documented for this time interval, but the plants and insects are virtually unknown, and are rare globally. This scarcity of data has hampered studies of the evolution and diversification of life, and has precluded detailed reconstructions and analyses of ecosystems of this critical period in Earth’s history. Here we introduce a new locality in the southern Karoo Basin that is producing exceptionally well-preserved and abundant fossils of novel freshwater and terrestrial insects, arachnids, and plants. Within a robust regional geochronological, geological and biostratigraphic context, this Konservat- and Konzentrat-Lagerstätte offers a unique opportunity for the study and reconstruction of a southern Gondwanan deltaic ecosystem that thrived 266–268 million years ago, and will serve as a high-resolution ecological baseline towards a better understanding of Permian extinction events.

- Description: Here we describe a new genus and four new species of the extinct ‘Grylloblattida’: Liomopteridae Sellards, 1909: Liomopterum connexus Cawood and Nel, n. sp., Liomopterum daenerys Cawood and Nel, n. sp., Colubrosopterum karooensis Cawood and Nel, n. gen., n. sp., and Paraliomopterum sp. The fossil wings were collected from a new Middle Permian locality near Sutherland, Northern Cape, South Africa, with the horizon close to the Ecca-Beaufort Group contact in the southern Karoo Basin.
