synclines and assigned to the family
Parahexacrinidae. Furthermore, “Hexacrinites
sp.” sensu Głuchowski (1993),
from the Upper Frasnian of the Holy
Cross Mountains (Poland), is transferred
to the family Parahexacrinidae and classified
as Parahexacrinitidae sp. I. comb.
nov. Numerous parahexacrinitid species
were erected based on the description of
isolated columnals. New material from
the Eifel proved that several of these
species are not distinguishable from
other crinoid groups, which is demonstrated
for “Parahexacrinus ellipticus”
and Melocrinites pyramidalis.

泥 盆 纪 Helianthasteridae 科 ( 海 星 纲 :
棘 皮 动 物 门 ) 的 重 新 评 价 = Reevaluation
of the Devonian family Helianthasteridae

Echinodermata). ( 英 文 ). Blake D B. Palaeontologische
Zeitschrift, 2009, 83(2):
293-308
Because of their taxonomic and morphologic
diversity, the asteroids of the
Lower Devonian Hunsruck Slate of
Germany are important to both an understanding
of the history of the class
Asteroidea and to the interpretation of
community evolution during the Paleozoic.
The Helianthasteridae Gregory is
restricted to Helianthaster and Arkonaster
Kesling, 1982 (Middle Devonian,
Canada); Lepidsterella Schuchert is
similar to other two genera but known
specimens are of poor quality and as resut
the status of the genus is uncertain.
Neither Helianthaster nor other Hunsruck
asteroids appear closely linked to
the crown group; instead, functional patterns
apparently re-emerged through
time, although identification of specific
behavior of ancient asteroids is difficult
to impossible.

New Catillocrinidae Allocatillocrinus
rarus sp. nov., with a previously unknown
tegmenal structure, Paracatillocrinus
shamovi sp. nov., and P. shakhtauensis
sp. nov., with an unusual relative
position of the crown and stem are
described from the Artinskian Stage
(Lower Permian) of the western slope of
the Middle and Southern Ural Mountains
(Boets, Krasnoufimsk, and Shakh-
Tau localities). The genus Allocatillocrinus
has not previously been recorded
from the Permian, while Paracatillocrinus
has only previously been reported
from the Upper Permian of Timor
Island.

Two new monotypic genera and a
new monotypic family Rozanovicystidae
of the class Cincta are described from
the Middle Cambrian (Mayaktakh Formation)
of the northeastern part of the
Siberian Platform. Based on data obtained
by morphofunctional analysis,
there is a possibility that these animals
could move by jet propulsion by ejecting
water from the opercular aperture. Probable
homologies of the main skeletal
parts are discussed.
