We describe a new megaloolithid locality discovered near Coll de Nargó (Catalonia, northeastern Iberian Peninsula). Eggs at the Pinyes site occur within extensively developed, vertically-stacked paleosols of an alluvial system. Eight clutches were excavated and mapped and biological and taphonomic aspects recorded. Three-dimensional maps were constructed using a Trimble total station, supplementing traditional planview mapping to allow more accurate interpretation of egg and clutch distribution. The Megaloolithus siruguei eggs are compressed, presenting an ellipsoidal shape. The three-dimensional geometry of two large clutches suggests that the eggs were laid in shallow, bowl-shaped depressions. Tangential thin sections of eggshells also reveal abundant... |
