...Michael J. Newman; Jan L. Den Blaauwen Abstract The Givetian (Middle Devonian) antiarch Asterolepis thule was first described in 1932 and its stratigraphical horizon was poorly understood as were all the Devonian deposits in the SE of Shetland (South East Shetland Group). Since that time a greater...

...John W. Wells Abstract Asterolepis chadwicki n. sp., from the lower part of the Upper Devonian continental Katsberg Formation, at Parksville, Sullivan County, N. Y., is the first record of this genus of antiarch fish in North America. Six plates of posterior trunk armor of one individual...

.... A poorly defined biozone containing rare individuals of the antiarch, Asterolepis orcadensis , occurs in a limited interval near the top of the lacustrine sequence. Based on the identification of these biozones and their relationship to distinct sedimentary units, we have provisionally identified within...

... characters listed above and it is not possible on this basis to identify it further. However, the oval shape of the anterior median dorsal ( Fig. 5.4 ) is more similar to that seen in Asterolepis than the same plate in Bothriolepis. It should be noted, however, that the two families show separate...

... to be purely Early Devonian, Dehler ( 1995 ) distinguished them as the Spring Mountain Beds. Denison ( 1968 ) described a vertebrate fauna from this channel that included Psephaspis idahoensis , Holonema haiti , and Asterolepis sp., which shows strong similarities to that from the Yahatinda Formation...

Many other genera are reported to occur in both regions, such as Watsonosteus, IDickosteus, Asterolepis, Dipterus, Glyptolepis, Gyroptychius, Thursius, Cheirolepis, Diplacanthus and Cheiracanthus ( Kleesment et al. 1997 ; Mark-Kurik 2000 ).

Fossils are represented by rare, often fragmented and abraded fish remains (plates of Asterolepis radiata Roh. and Bothriolepis cf. celullosa Pander and scales of Glyptolepis sp. are predominant) as well...
