Three-dimensional fossils are preserved
as flat impressions at random horizontal
levels. Bilateral symmetry discovered in
the ontogeny of Palaeophragmodictya
spinosa sp. nov. supports the hypothesis
of initial bilaterality of Cnidaria.

This paper deals with the revision of
the species of the genera Mucroserpula,
Propomatoceros, and Spiraserpula
(family Serpulidae) from the Upper
Callovian of the locality Peski (Moscow
Region). All taxa are described in accordance
with the current classification of
fossil serpulid tubes. Two new species
are described: Propomatoceros barskovi
sp. nov. and Spiraserpula oligospiralis
sp. nov.

Representatives of the families Serpulidae
and Sabellidae from the Upper
Callovian of the locality Peski (Moscow
Region) are described in accordance
with the current state of supraspecific
systematics. Species of the genera Cycloserpula,
Filogranula, Tetraserpula,
and Metavermilia are revised. One of the
genera, Cycloserpula, which was previously
assigned to the family Serpulidae,
is transferred to the family Sabellidae. A
new replacement name, Metavermilia
goldfussi nom. nov., is proposed for the
species that was previously described as
Serpula tricarinata Goldfuss, 1831.

The association of isolated remains of
lobopods with a netlike structure, including
plates of Microdictyon rozanovi
sp. nov. and sclerites with spinelike
process of Onychomicrodictyon
spiniferum gen. et sp. nov., as well as
saberlike sclerites of Protohertzina yudomica
sp. nov. interpreted as grasping
spines of chaetognaths, is described
from the middle part of the Inikan Formation
of the Toyonian Stage of the
Lower Cambrian (Lermontovia
dzevanovskii Zone). The diagnoses and
species composition of the genera Microdictyon
and Protohertzina are refined.

The study of the central nervous system
in extinct vertebrates is discussed.
Historical development of the nervous
system is restricted to a few morphological
patterns. The foundation of structural
conservatism of the nervous system
is provided by the multifunctional character
of any adaptive changes in the
brain of vertebrates. The functional
structural features allow the use of the
nervous system for the resolution of
some difficult questions of vertebrate
evolution.
