Depositional setting and early diagenesis of the dinosaur eggshell-bearing Aren Fm at Bastus, Late Campanian, south-central Pyrenees

Transitional environments of the lower Maastrichtian South-Pyrenean Basin (Catalonia, Spain): The Fumanya Member tidal flat

“…6 and 7). The barrier island or barrier features of the Areny sandstone are also found in several stratigraphic positions within this formation (see the detailed sedimentological study in Díaz-Molina et al, 2007). In Section 22 (Cadí unit) the Fumanya Mb tops the shelf sediments (no restricted shelf is observed), suggesting a hiatus in a section that is generally more condensed.…”

“…The Areny sandstone is poor in complete invertebrate remains, although mollusc fragments can be found (mainly rudists and other bivalves). Regarding vertebrates, this sandstone contains dinosaur remains, such as bones (Pereda-Suberbiola et al, 2009 and references) and eggs (Díaz-Molina et al, 2007;L opezMartínez & Vicens, 2012;Sanz et al, 1995).…”

Porosity of Late Paleocene Ornitholithus eggshells (Tremp Fm, south-central Pyrenees, Spain): Palaeoclimatic implications

“…Most of them are from Upper Cretaceous coastal deposits of the interfingering Aren and lower Tremp Fms (Sanz et al, 1995;López-Martínez et al, 2000;Díaz Molina et al, 2007). The abundance of fossil eggshell sites from Upper Campanian to Upper Maastrichtian deposits contrasts with its rarity or absence from the uppermost part of Maastrichtian and most Palaeocene deposits.…”

Dinosaur egg deposits in the Cretaceous Gyeongsang Supergroup, Korea: Diversity and paleobiological implications

“…Although diverse kinds of dinosaur eggs have been reported from many countries around the world (Carpenter and Alf, 1994;Weishampel et al, 2004) since the first discovery of dinosaur eggs in the Gobi Desert by Roy Chapman Andrews in 1923, the paleoenvironmental setting of dinosaur nesting areas was not well understood until the initiation of sedimentological and stratigraphic studies in the last two decades (Tandon et al, 1995;Varricchio et al, 1999;Lopez-Martinez et al, 2000;Mohabey, 2001;Cojan et al, 2003;Chiappe et al, 2004;Paik et al, 2004;Van Itterbeeck et al, 2004, 2005Therrien, 2005;Sankey, 2005a,b;Díaz-Molina et al, 2007;Salgado et al, 2007;Saneyoshi et al, 2008;Fanti and Miyashita, 2009;Kim et al, 2009;Liang et al, 2009;Grigorescue et al, 2010). The geographic occurrences, depositional ages, paleoenvironments, and lithology of dinosaur-egg-bearing deposits documented from both previous studies and the present work ( Fig.…”

“…Although most studies of dinosaur eggs have focused primarily on taxonomy, recent work on taphonomy and paleoenvironments of dinosauregg-bearing deposits has addressed their sedimentology (Tandon et al, 1995;Mohabey, 2001;Cojan et al, 2003;Chiappe et al, 2004;Paik et al, 2004;Van Itterbeeck et al, 2004, 2005Therrien, 2005;Díaz-Molina et al, 2007;Saneyoshi et al, 2008;Kim et al, 2009;Liang et al, 2009;Grigorescue et al, 2010). Such studies have provided useful information about the habitats and behavior of dinosaurs.…”
