serrations is unique among Pennsylvanian<br />
species of Orthacanthus. Teeth with often<br />
highly asymmeteical bases with an aborallyflexed<br />
lingual marginal flange and a single<br />
intermediate cusp are assigned to Triodus<br />

A partial rostrum of Propristis schweinfurthi<br />
dames, 1883 was collected in the Bartonian<br />
strata of northeastern Spain. The specimen<br />
represents the second record of the species<br />
from Europe, and the second occurrence<br />
of a sawfish (Mesopristis osonensis Farres,<br />
2003) from the Vic-Manlleu Marls Formation.<br />
In spite of some evidence to the contrary,<br />
Propristis probably preferred ecological conditions<br />
similar to extant sawfishes, i.e., inhabiting<br />
nearshore tropical to subtropical seas<br />
with occasional excursions into freshwater.<br />

tholichthys larval stage of butterfly fishes<br />

The fist fossils of the tholochthys larval<br />
stage of a chaetodontid from the lower Oligocene<br />
of frauenweiler are described, along with<br />
two less well-preserved probable tholochthys<br />
from the lower Oligocene Menilite-Formation<br />
of Prezemysil. The fossils are compared with<br />
tholochthys larvae of the extant genus of<br />
Chaetodontidae to which they are most similar,<br />
namely Chaetodon.<br />

The bothriolepidid placoderms Bothriolepis<br />
markovskii sp. nov. from the southern Ural<br />
Mountains and Bothriolepididae gen. et sp.<br />
indet. from the Kuznetsk Coal Basin are described.<br />
The new species from the southern<br />
Ural Mountains has a high dorsal crest, resembling<br />
in this character Scottish B. cristata<br />
Traquair, Australian B. gippslandiensis Hills<br />
and B. cullodenensis Long, and B. heckeri<br />
Lukševičs from the Novgorod Region. The<br />
bothriolepidid from the Kuznetsk Coal Basin<br />
is similar to Bothriolepis from central Poland<br />
and Livnolepis from European Russia. The<br />
new finds expand the diversity and distribution<br />
of crested bothriolepidid antiarchs. Apparently,<br />
the high bone dorsal crest developed<br />
in parallel in the exoskeleton of different bothriolepidid<br />
groups.<br />

Horseshoeichthys armaserratus, gen. et sp.<br />
nov., (Clupeomorpha: Ellimmichthyiformes:<br />
Sorbinichthyidae) is described from the<br />
Horseshoe Canyon Formation (Maastrichtian),<br />
Albertosaurus bonebed locality, Alberta, Canada.<br />
Horseshoeichthys armaserratus is classified<br />
as an ellimmichthyiform based on the following<br />
characters: the presence of a sixth infraorbital<br />
with a sensory canal that leads to the<br />
fifth infraorbital, absence of a supraorbital<br />
bone, subrectangular predorsal scutes, parietals<br />
in contact with each other at the midline,<br />
and two supramaxillae. The specimen is classified<br />
in the Sorbinichthyidae Family as it has<br />
abdominal ribs articulating in pits on the centra,<br />
posterior spines on predorsal scutes, and<br />
absence of a median spine on predorsal scutes.<br />
A new genus and species is proposed based on<br />
the presence of (anteriorly) Y-shaped mesethmoid,<br />
supraorbital, subrectangular predorsal<br />
scutes with coarse, rounded serrae on the<br />
posterior margin and a large anterior projection,<br />
scales with serrae on the circuli, and two<br />
postcleithra. This specimen represents the first<br />
freshwater ellimmichthyiform from the Upper<br />
Cretaceous of North America and the highest<br />
