The late Barremian ecosystem of Las Hoyas sustained by fishes and shrimps as inferred from coprofabrics

Las Hoyas, a locality of the La Huérguina Formation in the southwestern Iberia Basin (Cuenca province, Spain), is a well-known late Barremian Konservat-Lagerstätte highly rich in coprolites that have a wide variety of morphologies. Thin sections of twenty specimens were prepared from seven coprolite morphotypes. All of the examined coprolites exhibit a microcrystalline calcium phosphate groundmass lacking recrystallization and containing fine...
