“…The thin encrusting to warty morphology of the algae also suggests low to moderate energy and deep settings (Bosence, 1983(Bosence, , 1985. Similar algal frameworks form modern buildups in deep fore-reef settings (60-110 m) in the southern Great Barrier Reef (Marshall et al, 1998), Gulf of Mexico (Minnery et al, 1985), and Pleistocene deep-water buildups in the Huon Gulf, Papua New Guinea (Webster et al, 2004). Based on their morphology and species composition, the Hawaiian coralline algal crust limestone developed in deep fore-reef settings (Ͼ60-200 m).…”

We present evidence that the drowning of the ؊150 m coral reef around Hawaii was caused by rapid sea-level rise associated with meltwater pulse 1A (MWP-1A) during the last deglaciation. New U/Th and 14 C accelerator mass spectrometry dates, combined with reinterpretation of existing radiometric dates, constrain the age of the coral reef to 15.2-14.7 ka (U/Th age), indicating that reef growth persisted for 4.3 k.y. following the end of the Last Glacial Maximum at 19 ka. The drowning age of the reef is roughly synchronous with the onset of MWP-1A between 14.7 and 14.2 ka. Dates from coralline algal material range from 14 to 10 cal ka (calibrated radiocarbon age), 1-4 k.y. younger than the coral ages. A paleoenvironmental reconstruction incorporating all available radiometric dates, high-resolution bathymetry, dive observations, and coralgal paleobathymetry data indicates a dramatic rise in sea level around Hawaii ca. 14.7 ka. Paleowater depths over the reef crest increased rapidly above a critical depth (30-40 m), drowning the shallow reef-building Porites corals and causing a shift to deepwater coralline algal growth, preserved as a crust on the drowned reef crest.

“…During the rhodolith growth the biotic composition of the rhodoliths reflects changes in some environmental parameters such as water temperature and bathymetry (e.g., Minnery et al 1985;Steller and Foster 1995;Foster et al 1997;Foster 2001;Bassi et al 2012a). Variations in biotic composition as well as differences in coralline algal mor phology can be used to assess the paleoecological settings of fossil rhodolith beds (e.g., Basso and Tomaselli 1994;Braga and Aguirre 2001;Nebelsick et al 2005;Nalin et al 2008;Bassi et al 2012a).…”

“…Parachaetetes asvapatii, which is present in abundance is known to occur in lagoonal deposits having patchreefal encrustations (Wray, 1977). The associated Polystrata alba, though in low frequency, also forms reefal encrustations and frequently colonizes the relatively deeper (<30 m) bottoms (Bassi, 1998;Minnery et al 1985;Rasser and Piller, 1997). The other type of algal assemblage recorded from the Olaipadi quarry near Govindarajapatnam consists of Melobesioideae gen. et spec.…”

The present paper records eight Rhodophycean taxa from the Kallakudi limestone of the Uttatur Group (Lower Cretaceous) exposed in the quarries at Kallakudi and Olaipadi near Govindarajapatnam of the Cauvery Basin, south India. Of these, four species (Melobesioideae gen. et sp. indet 1, Melobesioideae gen. et sp. indet 2, Lithophyllum alternicellum and Pseudoamphiroa propria) belong to corallinaceae family, one species (Polystrata alba) is assigned to Peyssonneliaceae family, two species (Solenopora urgoniana and Parachaetetes asvapatii) are placed under Solenoporaceae; and one species (Sporolithon sp.) is referable to Sporolithaceae family. Among these, three taxa (Solenopora urgoniana, Lithophyllum alternicellum and Pseudoamphiroa propria) are recorded for the first time from India. The study also includes observations on ultrastructural morphological features of Parachaetetes asvapatii. The observations reveal absence of cell fusions, which confirms its affinities with Solenoporaceae. Palaeoecological data indicate that the assemblage from the sequence at the Kallakudi quarry is characteristic of lagoonal to reefal environment, whereas the Olaipadi quarry sequence near Govindarajapatnam points to 20 m to 30 m deep environment characterized by high-to moderate energy conditions.
