The earliest record of terrestrial animals in Gondwana: A scorpion from the Famennian (Late Devonian) Witpoort Formation of South Africa
The new genus and species, Gondwanascorpio emzantsiensis, are described in Scorpiones incertae se dis on the basis of fragments from the Famennian (Late Devonian) Waterloo Farm locality near Grahams town, Eastern Cape, South Africa. This finding adds to the sparse record of Late Devonian scorpion taxa and provides the first evidence of Palaeozoic scorpions from Gondwana. Material includes a com...
متن کاملA new Trimerocephalus species (Trilobita, Phacopidae) from the Late Devonian (Early Famennian) of Poland.
This study presents a detailed morphological analysis of a new species belonging to the blind trilobite Trimerocephalus McCoy, 1849, T. chopini n. sp., based on exceptionally well preserved articulated specimens from the Late Devonian (Early Famennian) of the Holy Cross Mountains in central Poland. The occurrence of this taxon in Kowala Quarry near Kielce has been reported previously, with spec...
متن کاملA new genus of lungfish from the Givetian (Middle Devonian) of central Australia
A new Dipterus−like lungfish, Harajicadipterus youngi, is described from the Givetian (Middle Devonian) Harajica Sand− stone Member of central Australia. The material is comprised of five specimens representing the skull roof, orbital bones, tooth plates, operculo−gular bones, a partial pectoral girdle, centra and scales. Harajicadipterus can be distinguished from other dipnoans by its long pos...
متن کاملAir-breathing adaptation in a marine Devonian lungfish.
Recent discoveries of tetrapod trackways in 395 Myr old tidal zone deposits of Poland (Niedźwiedzki et al. 2010 Nature 463, 43-48 (doi:10.1038/nature.08623)) indicate that vertebrates had already ventured out of the water and might already have developed some air-breathing capacity by the Middle Devonian. Air-breathing in lungfishes is not considered to be a shared specialization with tetrapods...
متن کاملEarly evolution of the lungfish pectoral-fin endoskeleton: evidence from the Middle Devonian (Givetian) Pentlandia macroptera
*Correspondence: Zerina Johanson, Department of Earth Sciences, Natural History Museum, Cromwell Road, London SW75BD, UK e-mail: [email protected] As the closest living relatives of tetrapods, lungfishes are frequently used as extant models for exploring the fin-to-limb transition. These studies have generally given little consideration to fossil taxa. This is because even though lungfish fi...
