..., the parasymphysial plate and the Meckelian ossification form the anterior border of a conspicuous fossa (Fig.  2 , pc.f). This fossa is situated in a region topologically congruent with the precoronoid fossa of the osteolepiform Cladarosymblema narrienense ( Fox et al. 1995 ) and likely represents the rhizodontid...

... with indeterminate arthrodires), Osteolepiformes, and Porolepiformes. This report documents for the first time that pteraspidids, considered to be organisms characteristic of the Lower Devonian elsewhere, lingered to the end of the Middle Devonian in western North America. This fauna is similar to others occurring...

...-ichthyostegalian tetrapods. Although the presence of an adsymphysial tooth plate in this specimen is regarded as the retention of an osteolepiform feature, the tusk and replacement pit on this dermal bone may be unique to this taxon. The poor preservation of the lower jaws associated with some previously described...
