Functional Morphology in Vertebrate Paleontology
Placoderm versus osteichthyan dermal bone patterns One of the great puzzles of
fish phylogeny is the relative phylogenetic position of the Placodermi. Can they
be related in any way to other gnathostomes? The problem is that their dermal ...

The uncertainty results partly from a lack of information available for Psarolepis
and other important stem taxa in the data set, and partly from the dificulty of
selecting and polarizing characters when both osteichthyan and non-
osteichthyan ...

Assembling the Tree of Life
Over the course of osteichthyan history, these diverticula become modified for
radically different functions that range from respiration, to buoyancy regulation, to
communication. In most terrestrial members of the clade, lungs completely
replace ...

Major Events in Early Vertebrate Evolution
Here the finds of new basal osteichthyans as well as new basal taxa in the two
osteichthyan subgroups changed the situation. The study of Psarolepis (Yu 1990;
1998; Zhu and Schultze 1997; Zhu et al. 1999) provides us with a morphological
...

As regards the Osteichthyan basal neighborhoods B, and B2, considerable
regional differences in one and the same form, as well with respect to different

Until now, no definitive osteichthyan characters have been recognised in
Lophosteus, with most evidence contradicting an osteichthyan affinity. Its dermal
bones have open rather than closed sensory line canals. No endochondral bone

Introduction Amongst the osteichthyan fishes several names have been given to
the tissue forming the outer covering to the oral teeth, assumed to result from ...

Fishes of the Okefenokee Swamp
These are the chondrichthyan (or cartilaginous) fishes, which include the sharks,
skates, and rays, and the os- teichthyan (or bony) fishes. The osteichthyan fishes
include almost all the remaining forms of fishes with which the reader is familiar.
Joshua Laerm, B. J. Freeman, 2008
It is unclear how the common osteichthyan ancestor of actinopterygians and
sarcopterygians arose from nonosteichthyan gnathostome ancestors. Zhu et al. (
1999) reported a 400-million-year-old sarcopterygianlike fish (Psarolepis) from (a
) (b) ...
