Discovery of the Cambrian Trace Fossil Thalassinoides


During the field trips carried out by a research team from the Department of Earth Sciences, Sultan Qaboos University, under supervision of Dr. Mohamed El-Ghali to study Haima Supergroup in Huqf Area (Governorate of Al Wusta), within the awarded strategic project funded by His Majesty (# SR/SCI/ETHS/15/01), a discovery of Thalassinoides trace fossil (Late Cambrian) was made. The discovered Thalassinoides are well preserved and cover a wide area within middle Miqrat Formation. This discovered Thalassinoides comprises cylindrical burrows (ca. 8 mm – 5 cm diameter) that form horizontal branching (10 - 22 cm long) polygonal network with shafts connected to the surface.

It is well known that Cambrian Thalassinoides is rare and poorly documented and of a small scale compared with those discovered within middle Miqrat Formation. This discovery will open doors for researchers to investigate and do research to know more about Cambrian life. This discover, as well, will help to reinterpret the proposed depositional environment of Miqrat Formation formerly. The Thalassinoides is well known to form by a variety of marine organisms. Many samples have been collected for further analysis in the Department of Earth Sciences and College of Science Labs, SQU and publish the results in high impact factor journals.
