Abstract: A new metazoan, Skeemella clavula gen. et sp. nov., is described from the Middle Cambrian Pierson Cove Formation of the Drum Mountains, Utah, USA.Skeemella is similar to vetulicolians, but differs from other examples of this group in the relative proportions of the anterior and posterior sections, the large number of divisions, and the elongate bifid termination.Synthesized stratigraphic column of the Zhujiaqing section (Series 2, Stage 4, Cambrian) in Dahai village, Huize, Yunnan and the main occurences of Guanshan Biota in Yunnan, southwest China.Phylum Vetulicolia, plus newly recognized early Cambrian chordates, lend weight to the concept of a sudden, rather than muted and long-drawn-out, Cambrian Explosion [5–7]. 2. Chinese BreakthroughNa escala de tempo geológico, o Cambriano ou Câmbrico é o período da era Paleozoica do éon Fanerozoico que está compreendido entre há 542 milhões e 488 milhões de anos, aproximadamente. O período Cambriano sucede o período Ediacarano da era Neoproterozoica ou precambrico do éon Proterozoico e precede o período Ordoviciano de sua era.
