Vyatkian Gorizont (uppermost Tatarian) approximately<br />
50 m below the local Permian/Triassic<br />
boundary. Seventeen randomly<br />
orientated footprints were excavated and are<br />
referred to the ichnospecies Brontopus giganteus.<br />
The footprints were emplaced in a reddish-brown<br />
mudstone that was deposited from<br />
suspension beneath shallow ponded water in a<br />
floodplain environment. They were subsequently<br />
cast by the base of the overlying finegrained<br />
sandstone, which was deposited from<br />
a sheet-flood event. The footprints were produced<br />
by a large therapsid, possibly a dinocephalian,<br />
but more probably a dicynodont,<br />
and represent the first ichnological record of<br />
the Therapsida from the Upper Permian of<br />
Russia.<br />

Well-preserved Archean pillow lavas from<br />
the ca. 3.35 Ga Euro Basalt of the Pilbara Craton,<br />
Western Australia, contain micron-sized<br />
tubular structures mineralized by titanite (Ca-<br />
TiSiO 4 ) with residual organic carbon preserved<br />
along their margins. Direct U-Pb dating<br />
of titanite in the tubular structures demonstrates<br />
an Archean age. These tubular microstructures<br />
are identical to microbial ichnofossils<br />
in modern basalts, ophiolites, and greenstone<br />
belts, and are interpreted as a biogenic<br />
signature in these ancient rocks. Microbial<br />
colonization of basaltic glass thus appears to<br />
have been part of a deep subsurface biosphere<br />
established early in Earth's history.<br />

分 子 古 生 物 学 = Molecular Palaeobiology.<br />

For more than a generation, molecular biology<br />
has been used to approach palaeontological<br />
problems, and yet only recently have attempts<br />
been made to integrate research utilizing<br />
the geological and genomic records in uncovering<br />
evolutionary history. We codify this<br />
approach as Molecular Palaeobiology for<br />
which we provide a synthetic framework for<br />
studying the interplay among genotype, phenotype<br />
and the environment, within the context<br />
of deep time. We provide examples of<br />
existing studies where molecular and morphological<br />
data have been integrated to provide<br />
novel insights within each of these variables,<br />
and an account of a case study where each<br />
variable has been tackled to understand better<br />
a single macroevolutionary event: the diversification<br />
of metazoan phyla. We show that the<br />
promise of this approach extends well beyond<br />
research into the evolutionary history of animals<br />
and, in particular, we single out plant<br />
evolution as the single greatest opportunity<br />
waiting to be exploited by molecular palaeobiology.<br />
Although most of our examples consider<br />
how novel molecular data and techniques<br />
have breathed new life into longstanding<br />
palaeontological controversies, we<br />
argue that this asymmetry in the balance of<br />
molecular and morphological evidence is an<br />
artefact of the relative ‘newness’ of molecular<br />
data. In particular, palaeontological data provide<br />
unique and crucial roles in unravelling<br />
evolutionary history given that extinct taxa<br />
reveal patterns of character evolution invisible<br />
to molecular biology. Finally, we argue that<br />
palaeobiologists, rather than molecular biologists,<br />
are best placed to exploit the opportunity<br />
afforded by molecular palaeobiology, though<br />
this will require incorporating the techniques<br />
and approaches of molecular biology into their<br />
skill-set.<br />
