In search of the kingdom's Ediacarans: the first genuine Metazoans (macroscopic body and trace fossils) from the Neoproterozoic Jibalah Group (Vendian/Ediacaran) on the Arabian Shield
Ediacarans make up the oldest known truly diverse metazoan assemblages and are known globally. However, few sites have produced abundant fossils, and until recently such fossils were unknown in Arabia. Generally restricted to the late Neoproterozoic, the best known assemblages occur in China, Newfou...

Ediacarans make up the oldest known truly diverse metazoan assemblages and are known globally. However, few sites have produced abundant fossils, and until recently such fossils were unknown in Arabia. Generally restricted to the late Neoproterozoic, the best known assemblages occur in China, Newfoundland, the White Sea in northern Russia, the Flinders Ranges of South Australia and southern Namibia in Africa. Less diverse assemblages are known from Siberia, Ukraine, UK, and a few sites in Asia, and North and South America. Ediacarans occur primarily in shallow marine derived sands and clays with the exception of Newfoundland forms that may have inhabited light free depths in a volcanically active terrane. They are known in rock sequences dating from 630 Ma to 540 Ma, the Ediacaran or Vendian period, the youngest division of Precambrian time. New discoveries in Saudi Arabia over the past 5 years have brought to light the presence of Ediacarans, both traces and body fossils, suggesting that further investigation most likely will yield a much more diverse assemblage, and one that may well have inhabited less saline environs that is typical for other Ediacarans.
