- The unidentified dinosaur egg clutches (Fig. A-B). You know that oviraptorosaurian egg clutches can be identified based on the following characteristics (C1-C5): C1. Elongate egg shape C2. Asymmetrical egg shape (more pointed at one end) C3. Eggs are arranged in three or four circular rings C4. Eggs are paired (arranged in clusters of two) C5. May be associated with oviraptorosaurian bones Egg clutches that match 3 or more of characteristics C1-C5 belong to oviraptorosaurians.
