Extract

Cambroclayes are Cambrian phosphatized problematica. The group is known from spine-like remains that are locally abundant on a number of Cambrian paleocontinents. Cambroclaves are known through a relatively short time interval (late Early Cambrian-early Middle Cambrian) mostly from tropical, carbonate platform successions on the Siberian Platform, East Gondwana (Australia, China, Kazakhstan), and West Gondwana. The West Gondwana occurrences include Cambroclavus ludwigsdorfensis Elicki, 1994 and Cambroclavus sp. from the late Early Cambrian of eastern Germany (Elicki, 1994, 2005; Elicki and Watte, 2003), and Cambroclavus sp. from the early Middle Cambrian of Sardinia (Elicki and Wotte, 2003;“ Elicki et al., 2003; Elicki, 2005, 2006). Recently, Clausen and Alvaro (2006) reported the zhijinitid form Parazhijinites cf. guizhouensis Qian and Yin, 1984 from the early Middle Cambrian of the Cantabrian zone of northwest Spain. Other than the mentioned tropical occurrences, Landing (1991) published the obviously cool to cold water form Samsanoffoclavus matthewi Landing, 1991 from the middle Early Cambrian of Cape Breton Island (Avalonia).
