In addition, belemnite rostra were bored by endolithic
organisms at the seafloor (Reolid and Benito, 2012 and Benito and Reolid, 2012) and our observations indicate that the non-fluorescent calcite precipitated prior to belemnite rostra were bored; in particularly, borings cross-cut both fluorescent and non-fluorescent calcite (Fig.
Samples of endolithic
bacteria (bacteria that can live inside stones) will be collected along with bacteria found in sediments in the lakes.
"The most relevant outcome was that more than 60% of the cells of the endolithic
communities studied remained intact after 'exposure to Mars', or rather, the stability of their cellular DNA was still high," said Rosa de la Torre Noetzel from Spain's National Institute of Aerospace Technology (INTA), one of the co-authors of the study.
In addition to reducing observer bias, this also reduces possible bias by differences in the endolithic
structures, because the most dominant species are usually larger and often have more coherent endolithic
tissue than species with smaller specimens (as for sponges 1 and 4 in Fig.
The Mount Auburn Member of the Grant Lake Formation and its lateral equivalents in the Terrill Member of the Ashlock Formation was chosen because: 1) regional stratigraphic correlations were constrained to decimeter scale using a combination of key surfaces and marker beds (e.g., hardgrounds, erosional surfaces, major lithofacies offsets), as well as faunal epiboles in closely spaced outcrops along both sides of the Cincinnati Arch and 2) this interval extends laterally from desiccation-cracked, shaly facies to nodular, fossiliferous facies representing environments below normal wave-base that have been previously examined for microendoliths, traces of light-sensitive endolithic
cyanobacteria and green and red algae (Vogel & Brett 2009).
The "naked" rock outcrops of the CRs commonly exhibit a striation of dark and light vertical bands resembling a barcode, formed by colonies of epilithic and endolithic
Cyanobacteria and algae (Alves et al., 2002; De Sousa et al., 2006, 2007a, b).
