reflecting either independent mineralization of<br />
organic-walled sclerites in chancelloriids and<br />
halkieriids or the opening of a taphonomic<br />
window that favours coelosclerite preservation.<br />

Apart from previously reported Small<br />
Shelly Fossils (SSFs), a macroscopic fossil<br />
assemblage, comprising abundant algae, coneshaped<br />
tubular fossil forms, and probable<br />
impressions of a megascopic metazoan, comes<br />
from the Lower Cambrian Yanjiahe Formation<br />
in the Yangtze Gorges area of western Hubei<br />
Province, south China. The visible fossils are<br />
preserved in thinl aminated siltstone or muddy<br />
siltstone intercalated between 8-15 cm-thick<br />
carbonate deposits, probably representing<br />
sedimentary settings of a constrained local<br />
depression in the shallow water carbonate<br />
platform during the Early Cambrian<br />
Meishucunian Stage. The macroscopic fossil<br />
association provides significant fossil<br />
evidence about the evolution of life from the<br />
late Precambrian to the ' Cambrian<br />
explosion' interval.<br />

Diverse small shelly fossils and other<br />
associated fossils were recently recovered<br />
from the Cambrian Hanaeri section,<br />
southwestern Mungyeong, Korea. The fauna<br />
includes conoidal problematica, poriferans<br />
( sponge spicules ) , coeloscleritophorans<br />
( chancelioriids ) , brachiopods,<br />
monoplacophorans, trilobite ( )<br />
fragments, echinoderms, and conodonts. A<br />
preliminary assessment of faunal associations,<br />
stratigraphic implications, and the correlation<br />
of these skeletal fossils is given, based on<br />
occurrences of Actinotheca cf. mira (He),<br />

Four floristic assemblages mentioned in<br />
previous literature from four localities of<br />
central southern Chile are described.<br />
Localities are: Cerro Ranguili (Estero La<br />
Higuera Formation), Cerro Quilvo (La<br />
Patagua Formation or "Estratos de Pocillas"),<br />
Cerro Gupo (without stratigraphic<br />
denomination) and Rio Quillen (probably<br />
Huimpil-Llafquentue Formation). The plant<br />
list includes: Neocalamites sp., Cladophlebis<br />
sp., Dictyophyllum (T.)<br />
T rothi Frenguelli,<br />
Dictyophyllum (Thaumatopteris) sp.,<br />
Dicroidium odontopteroides (Morris) Gothan,<br />

Taeniopteris sp. b, Linguifolium cf. lillieanum<br />
(Arber) Retallack, Linguifolium sp. and<br />
Heidiphyllum elongatum (Morris) Retallack.<br />
At Cerro Ranguili and Cerro Gupo there is a<br />
certain chronologic control with marine<br />
invertebrates, but in any case the florules<br />
indicate an undoubtedly Upper Triassic age.<br />
