We observed that the amount of lithified
calcite on Cladophora sp.
It is possible that the differences between the lithified
and modern structures identified here and those that have been previously reported obey to two main factors: first, most reported MISS and microbial mat features have been observed and classified on coastal and hypersaline environments (Schieber, 1986; Gerdes, 2007; Schieber, 2007; Ulmer-Scholle et al, 2014), which might have contrasting conditions to the paleoenvironments in which the La Luna, Paja, and Tetuan formations were deposited.
Where cleavage is developed during tectonic deformation it can be difficult or impossible to determine whether pre-cleavage structures were developed in lithified
or unlithified sediments.
It is highly useful in shallow surveys of unconsolidated, non-lithified, partially consolidated and lithified
sediments (Wyatt et al., 1996; Buker et al., 1998; Bachrach et al., 1998; Bachrach and Nur, 1998; Steeples and Miller, 1998; Francese et al., 2007).
Just over 65 million years ago, when the animal died, this was not a lithified
sandstone and consisted of fine sand that was washed away by river streams and that was deposited, along with the remains of other turtles of the Barranc de Torrebilles, at the bottom of one of these rivers.
The only habitat known (Sand hills) consists of calcareous lithified
dunes, used for grazing then (Wilkes, 1856) so that it may have been introduced locally.
This means enough time elapsed for (1) formation of hardened limestone, (2) infusion of limestone with magnesium to become dolomite, (3) development of karst features in dolomite through interaction with weak carbonic acid in ground water, and (4) cementation (lithification) of sand and other sediments that worked their way into the solution features to form "rock inside rock." (16) A large block of this karsted dolomite is integrated into the overlying Sixty mile Formation, (17) meaning that enough time elapsed for it to be uplifted, broken off in a landslide, and integrated into a new sediment matrix which then lithified
into solid breccia.
According to the first hypothesis, arsenic is derived from 'erosion of lithified
sediments and crystalline rocks of the Himalayan range and adjacent regions' ,  and was deposited on floodplains across the lower delta where it was subjected to intense chemical weathering.
This area is known as the Oculina Bank, a series of reefs and high-relief bioherms (thickets of live coral, capping mounds of sediment and coral rubble, built upon an underlying lithified
base structure) constructed by the scleractinian ivory tree coral (Oculina varicosa).
This formation of Pleistocene limestone is believed to have been formed from lithified
calcareous sand dunes associated with ancient shorelines (Clarke 1975:79).
fossil mangrove trunks and rhizoliths (fossilised roots) are abundantly exposed along the outer parts of the wave-cut platform all along the northern coast (Fig.
