The former presents an interesting
speculation, but does not allow for
placement of findings within an ecological
and chronological context. Likewise,
the assignment of specimens as paleopathological
holotypes defeats this purpose
in attempting to narrowly define the
physical manifestation of the immune
response to disease, doing nothing more
than a photographic library of paleopathologies
could do, but not conveying
the true nature of paleopathologies and
could lead to artificial classification
schemes that would cause more confusion
than clarity.

Recent achievement in hydrocarbon
exploration in Northeast Sichuan demonstrated
that Permian calcareous and
argillaceous deposits are the major contributing
source rocks. Reevaluation on
the hydrocarbon potential of the Permian
strata over the whole Yangtze region is
thus to be desired. A comprehensive corroboration
was carried out at the Shangsi
Section, Guangyuan, Northeast Sichuan,
which is believed to be another promising
area in South China. This article
deals with the ecological and depositional
conditions of the Permian strata in
the section, including the Chihsia, Maokou,
Wujiaping, and Dalong formations,
which share some similarities with
those occurring in the broad Yangtze
carbonate platforms. Five fossil communities
of Mizzia-Permocalculus, Hayasakaia,
Inozoan, Ostracod, and Crinoid
were identified in the Yangtze region
and described in detail including
their components and occurrence. On
the basis of the fossil communities and
depositional features, 23 habitat types,
mainly occurring from inner to outer
shelves, were recognized at the Shangsi
Section in order to reconstruct the depositional
conditions and accordingly to
evaluate the paleoproductivity. In addition,
the subdivision of Chihsia Formation
in the section was revised, which
would be of significance for the reconstruction
of the Chihsian paleogeography
in the study area.

New total organic carbon (TOC) data
from the two Ordovician–Silurian transitional
graptolite-bearing black shale intervals,
the Wufeng Formation and the
Longmaxi Formation in Central
Guizhou and West Hubei, respectively,
as well as previously reported TOC data
from the same intervals in other places
on the Yangtze platform of South China,
have been used to produce an initial estimate
of the primary paleoproductivity
via a conventional inverse method (i.e.,
R pp-inverse ). The values of the R pp-inverse are
estimated to be 32 (43–21) gC/(m 2·a)
