英 国 Bedfordshire 郡 Leighton Buzzard 地<br />

Crinoids from the Shenley Limestone (Albian)<br />
of Leighton Buzzard, Bedfordshire, UK. ( 英<br />

Palaeontology, 2010, 8(3): 427-447<br />
A diverse and exceptionally preserved crinoid<br />
fauna is described from the Early Albian<br />
(Leymeriella tardefurcata Zone) Shenley<br />
Limestone of Leighton Buzzard (Bedfordshire,<br />
England). It is unusual in the presence of a<br />
number of species which are the last records<br />
of genera common in and typical of the Jurassic<br />
(the isocrinid Balanocrinus smithi sp. nov.,<br />
the millericrinids Apiocrinites gillieroni (de<br />
Loriol) and an unnamed species of<br />
Apiocrinites, and the cyclocrinid Cyclocrinus<br />
variolarius (Seeley)), in association with the<br />
first record of the typically Cretaceous<br />
Roveacrinidae (Discocrinus integer sp. nov.).<br />
Sclerocrinids (Cyrtocrinida) are represented<br />
by Torynocinus canon and Torynocrinus globosus<br />
sp. nov. The excellent preservation of<br />
the material permits new and taxonomically<br />
important observations to be made on cup<br />
structure in the sclerocrinid and roveacrinid<br />
species, and the first description of Torynocrinus<br />
brachials. Additionally, the material includes<br />
different growth stages and brachials<br />
which allow for extended diagnoses of known<br />
species. The fauna is also remarkable for the<br />
association of differently sized stalked crinoids<br />
attached either by cirri or holdfasts, and<br />
a pelagic roveacrinid.<br />

A diverse holothurian fauna from the Upper<br />
Turonian of the Isle of Wolin (northwestern<br />
Poland), is described and assessed with respect<br />
to palaeoecology, palaeobiology and<br />
evolutionary diversification. The fauna was<br />
recovered from chalk and partly silicified<br />
chalk. A stratigraphic re-assessment of all<br />
available biostratigraphic literature permits<br />
assignment to the Subprionocyclus neptuni<br />
ammonite zonal age (late Turonian). The majority<br />
of the holothurian fauna consists of apodid,<br />
aspidochirotid, and elasipodid species.<br />
The part of the fauna described here consists<br />
of sclerite species of three different Recent<br />
families of the Apodida. Two new forms, Calcancora<br />
venusta sp. nov. and Rigaudites ernsti<br />
sp. nov. (Synaptidae: Rynkatorpinae), are described,<br />
figured and discussed.<br />

A new stylophoran (Ceratocystis prosthiakida<br />
sp. nov.) from the early Middle Cambrian<br />
of the Franconian forest is described<br />
with the aid of computed tomography, a powerful<br />
means of visualizing fossil antomy. Investigation<br />
in this manner enabled previously<br />
inaccessible, buried parts of the fossil to be<br />
imaged and studied. In addition, a procedure<br />
for digitally correcting plate articulations was<br />
implemented.<br />

Crinoids and phiocistioids from classical<br />
fossil localities of the National Geosite<br />
"Schlade Valley", NE of Bergisch Gladbach<br />
are reported for the first time. The fossils were<br />
derived from the reefal Buchel Formation at<br />
the northern flank of the Bergisch Gladbach-<br />
Paffrath Syncline. From the abandoned quarry<br />
"Im Grubenfeld", skeletal elements of holothuroids,<br />
phiocistioids and crinoids are documented<br />
from a bituminous marly shale horizon<br />
in the middle Buchel Formation.<br />
