Data regarding associated microfossils
and radiometric ages were provided by Micropaleo Consultants, Inc.
: new evidence of ancient microbes.
Differentiating dietary and non-dietary microfossils
extracted from human dental calculus: The importance of sweet potato to ancient diet on Rapa Nui.
Caption: Crystals of pyrite mineral (black specks) that surround microfossils
from a 3.4-billion-year-old Australian rock layer may be evidence of early cell metabolism.
Assemblage of microfossils
caused to suggest 2 biozones; Pseudocyclammina lituus-Dukhania Arabica Algal-zone ll with Neocomian age and Orbitolina--Choffattella -Salpingoporella dinarica zone l with Barremian-early Aptian.
The dispute concerning the origin of the CIs on Mars, unlike an argument about microfossils
, was a more straightforward battle over isotopes and rock chemistry.
Within the last couple of decades, studies of plant microfossils
from the western Pacific have provided major advances in identifying prehistoric plant subsistence.
The use of microfossils
for correlation of the base of the Wenlock was investigated by Mabillard & Aldridge (1985), but they estimated that the base did not coincide with the base of any microfossil
Since early Ypresian microfossils
are present in Wenonah even though the Acadia chalk is not, it follows that this unit may in fact be late Ypresian in age.
Petrographically it consists of bioclastic, peloidal and intraclastic packstone-wackestones with abundant microfossils
of assemblages that are representative of the inner shelf environment (e.g.
But scientists are still not sure whether the microfossils
were really from Mars or the result of Earthly contamination.
