“…The Neoproterozoic land system was thus similar to recent arid regions, or the continental polar areas. The dominant terrestrial environment was alluvial plains with unstable riverbeds even though meandering rivers also occurred ( Barkat et al, 2020 ). Along the coast, there were river deltas and tidal flats where the eolic sedimentation of loess and wadded sands also took place ( Williams et al, 2008 ; Retallack, 2011 ).…”

For tens of millions of years (Ma), the terrestrial habitats of Snowball Earth during the Cryogenian period (between 720 and 635 Ma before present–Neoproterozoic Era) were possibly dominated by global snow and ice cover up to the equatorial sublimative desert. The most recent time-calibrated phylogenies calibrated not only on plants but on a comprehensive set of eukaryotes indicate that within the Streptophyta, multicellular charophytes (Phragmoplastophyta) evolved in the Mesoproterozoic to the early Neoproterozoic. At the same time, Cryogenian is the time of the likely origin of the common ancestor of Zygnematophyceae and Embryophyta and later, also of the Zygnematophyceae–Embryophyta split. This common ancestor is proposed to be called Anydrophyta; here, we use anydrophytes. Based on the combination of published phylogenomic studies and estimated diversification time comparisons, we deem it highly likely that anydrophytes evolved in response to Cryogenian cooling. Also, later in the Cryogenian, secondary simplification of multicellular anydrophytes and loss of flagella resulted in Zygnematophyceae diversification as an adaptation to the extended cold glacial environment. We propose that the Marinoan geochemically documented expansion of first terrestrial flora has been represented not only by Chlorophyta but also by Streptophyta, including the anydrophytes, and later by Zygnematophyceae, thriving on glacial surfaces until today. It is possible that multicellular early Embryophyta survived in less abundant (possibly relatively warmer) refugia, relying more on mineral substrates, allowing the retention of flagella-based sexuality. The loss of flagella and sexual reproduction by conjugation evolved in Zygnematophyceae and zygomycetous fungi during the Cryogenian in a remarkably convergent way. Thus, we support the concept that the important basal cellular adaptations to terrestrial environments were exapted in streptophyte algae for terrestrialization and propose that this was stimulated by the adaptation to glacial habitats dominating the Cryogenian Snowball Earth. Including the glacial lifestyle when considering the rise of land plants increases the parsimony of connecting different ecological, phylogenetic, and physiological puzzles of the journey from aquatic algae to terrestrial floras.

“…Sheet sandstones (SS), sheet conglomerates, and channelized (CH) conglomerates, in decreasing order of abundance, represent the mid fan. Whereas the SS units are identified as products of ephemeral fluvial channels, sheet conglomerates are interpreted as products of unconfined flows related to sheet flood events (McPherson et al, 1987;Chakraborty et al, 2009;Barkat et al, 2020). An intergradational relationship between sheet flood and stream channel deposits is a common observation in mid fan and is considered a hallmark character for alluvial fan succession (Rust and Koster, 1984).…”

“…In a parallel study, measurement of slope data from 430 modern alluvial fans (214 from humid climate, Japan, and 216 from arid climate, Death Valley and Owen valley, California) allowed Hasimoto et al (2008) to document humid fan slope values right within the "natural depositional gap" marked by Blair and McPherson (1994) and hence, question the validity of slope gap conjecture between alluvial fan and river systems in a humid climate. Certainly, the revised understanding prompted workers to raise doubt on the interpretation of Precambrian alluvial strata as a product of fan or fluvial origin since it is well appreciated that 1) enhanced slope failures, landslides and debris flow on hill slopes in absence of vegetation and soil cover may result in misinterpretation of scree cone and alluvial fan deposits as products of coarse-grained braided fluvial systems (Els, 1990;Eriksson et al, 1998;Bose et al, 2012;Barkat et al, 2020), and 2) reworking of a distal alluvial fan by a fluvial system in humid climate may incite misinterpretation of fan deposit as of braid plain origin.…”

“…Overbank and interfluvial deposits are largely underrepresented (Eriksson et al, 2008;Long, 2011). Going beyond this generalized idea, some recent studies (Owen and Santos, 2014;Santos and Owen, 2016;Barkat et al, 2020) documented the development of point bars and flood plains in Precambrian fluvial systems, particularly of Neoproterozoic time, which raised the question of whether the paucity of flood plain and meandering stream geometry in Precambrian alluvial records is environmentally triggered or more of a bias in preservation record of a fine-grained flood plain. In the absence of any modern-day analog for vegetationless meandering river systems in humid climates, the extent to which the meandering channel form developed in Precambrian alluvial systems remains uncertain.…”

“Present is the key to the past”—in this all-inclusive uniformitarians’ geological panacea, the Precambrian continental sedimentation system stands out as an odd candidate. The distinctive nature of Precambrian alluvial sedimentation, not analogous to their Phanerozoic counterparts, is highlighted in literature in the absence of rooted vegetation, soil, and an overall greenhouse atmospheric condition. Documentation from Precambrian alluvial deposits around the globe suggests a sedimentation pattern dominated by scree cones, alluvial fans, and braid-plains under the combined effects of aggressive weathering and absence of vegetation; ephemeral braid-plains convincingly outweigh the other alluvial systems in the rock record. It is also surmised that Precambrian fluvial systems, unlike their Phanerozoic-modern analogs, maintained unequivocal ephemeral character across different climatic zones with very less chance of assuming meandering channel planform in absence of buffering effects of rooted plant and adequate mud. Local ponding of muddy sediments, though visualized in some rare cases, was mostly connected with the generation of local paleoslope and unusual riverine hydrology. Recent studies, however, raised a question about the actual paucity of mud, documented meander channel planforms from Precambrian fluvial records, and drew a parallel between the character of the Pre-Silurian alluvial plain on the surface of Earth and meander channel planforms on the Martian surface, interpreted from satellite imagery data. From the collation of data on alluvial deposits from a number of Indian Precambrian basins, augmented by new data from the Bayana basin, a Paleoproterozoic basin in the North Delhi fold belt, the present study attempts to document nuances and intricacies in Precambrian alluvial sedimentation motif that include facies architecture and paleohydrology. From an extensive, though not exhaustive, database, the study intends to claim the establishment of a meander channel-form in Precambrian river systems at a local scale in areas of low discharge and availability of higher silt and mud.

For tens of millions of years (Ma) the terrestrial habitats of Snowball Earth during the Cryogenian period (between 720 to 635 Ma before present - Neoproterozoic Era) were possibly dominated by global snow and ice cover up to the equatorial sublimative desert. The most recent time-calibrated phylogenies calibrated not only on plants, but on a comprehensive set of eukaryotes, indicate within the Streptophyta, multicellular Charophyceae evolved in Mesoproterozoic to early Neoproterozoic, while Cryogenian is the time of likely Anydrophyta origin (common ancestor of Zygnematophyceae and Embryophyta) and also of Zygnematophyceae – Embryophyta split. Based on the combination of published phylogenomic studies and estimated diversification time comparisons we found strong support for the possibility Anydrophyta likely evolved in response to Cryogenian cooling, and that later in Cryogenian secondary simplification of multicellular Anydrophytes resulted in Zygnematophyceae diversification. We propose Marinoan geochemically documented expansion of first terrestrial flora has been represented not only by Chlorophyta, but also by Streptophyta – including the Anydrophyta – and later by Zygnematophyceae, thriving on glacial surfaces until today. It is possible multicellular early Embryophytes survived in less abundant, possibly relatively warmer refugia, relying more on mineral substrates allowing retention of flagella-based sexuality. Loss of flagella and sexual reproduction by conjugation evolved in Zygnematophyceae during Cryogenian in a remarkable convergent way as in Cryogenian-appearing zygomycetous fungi. We thus support the concept of the important basal cellular exaptations to terrestrial environments evolved in streptophyte algae and propose this was stimulated by the adaptation to glacial habitats dominating the Cryogenian Snowball Earth. Including the glacial lifestyle in the picture of the rise of land plants increases the parsimony of connecting different ecological, phylogenetic and physiological puzzles of the journey from aquatic algae to the terrestrial floras.
