It is of geological interest because its steep cliffs expose excellent examples of Ordovician Tumblagooda Sandstone, containing trace fossils of " Skolithos " and probably " Diplocraterion ".
2.
Around the start of the Cambrian ( about ), many new types of traces first appear, including well-known vertical burrows such as " Diplocraterion " and " Skolithos ", and traces normally attributed to arthropods, such as " Cruziana " and " Rusophycus ".
3.
In essence, the organism " escapes " from being buried too deeply by progressively tunneling upward, thereby leaving behind it a stacked vertical succession of concave-up spreite . " Diplocraterion " is the classic example of a vertical burrow with spreite, whereas " Rhizocorallium " is an example of a horizontal burrow with spreite.
4.
""'Diplocraterion " "'is an ichnogenus describing vertical U-shaped burrows having a spreite ( weblike construction ) between the two limbs of the U . The presence / absence of funnel-shaped openings should not be used as an ichnotaxobase due the high probability that the upper portions of the trace may have been eroded away.
