The morphological adaptation of Lithocodium aggregatum Elliott (calcareous green alga) to cryptic microhabitats (Lower Aptian, Spain): an example of phenotypic plasticity

Abstract: Lithocodium aggregatum Elliott is interpreted as a heterotrichale chlorophycean alga with a prostrate and erect system within a well-calcified tissue. Within Lower Aptian coral rubble of the western Maestrat Basin, Spain, it forms thick masses of juxtaposed crusts around the bioclasts. In achieving a rapid and complete encrustation of the available bioclasts, Lithocodium applied several strategies, e.g., filling voids of structured surfaces with a special fabric or forming erect extensions to bridge adjacent s… Show more

“…To a lesser extent, even the activity of infaunal soft- and mainly hard-substrate cryptobionts is known in marine paleoenvironments (see Uchman et al, 2003 and references therein). Today, the most common organisms with cryptic habits are algae, foraminifera, sponges, corals, polychaetes, mollusks, bryozoans, and brachiopods (Kobluk and Lysenko, 1993; Lukeneder and Harzhauser, 2003; Taylor and Wilson, 2003; Zuschin and Mayrhofer, 2009; Schlagintweit and Bover-Arnal, 2012).…”

“…According to many authors (e.g., Tucker and Wright, 1990;Leinfelder, 2001;Schlagintweit and Bover-Arnal, 2012), Lithocodium aggregatum is a depth indicator (representing a water depth of 10 to 20 m) and occurrence of this flora suggests a shallow-water settings above the fair-weather wave base, such as inner ramps. On the other hand, Banner and Simmons (1994) stated that the micritic matrix of lithocodium indicates low paleocurrent velocities (less than 10 cm/sec), and there considered more likely to have been in warm, marine, well oxygenated settings.…”

“…8) MF8 Foram-Algal Floatstone/Wackestone Description: The most characteristic component of the facies is large Lithocodium aggregatum clasts (green algae sensu) [24], associated with various large and small foraminifers (Orbitolina, Miliolids, Valvulinid) and oncoids. Other bioclasts are ostracods, algal debris (Salpingoporella), gastropod, and echinoderms debris.…”

On the other hand, the micritic matrix of Lithocodium indicates low palaeocurrent velocities (less than 10 cm/sec), and it is more likely to have been in warm, fully marine, well oxygenated mid ramp (15 to 60 m) [28].…”
