A group of Graphoglyptid burrows preserved as erosional casts on the sole of a sandy flysch turbidite. The Glockeria is very large and shows the characteristic U-shaped elements and erosional fluting in strong positive relief. The Lorenzinia shows the typical radiating structure with short subequal rays around a smooth central area. The Megagrapton shows the meshes of irregular shape and size. The three specimens are on a block about 320mm square. From between Guetaria and Zumaya, Northern Spain.

Size: 320mm x 320mm
