Renews Head Formation
The Renews Head Formation is a geologic formation in Newfoundland and Labrador. It preserves fossils dating back to the Ediacaran period.
Geology
The Renews Head Formation is primarily composed of laminated dark-gray silty sandstones which weathers to a rusty-brown, alongside thin to medium-bedded sandstones containing minor black shales throughout. There are also thick, cross-bedded laminated gray sandstones, which are structureless in nature, and are inter-bedded with more black shales and thin sandstones. With this, it has been suggested that these layers were deposited in a delta-front environment.It is overlain by the Cappahayden Formation near the town of Ferryland, and the Gibbett Hill Formation near the city of St. John's. Meanwhile the formation is gradationally and conformably underlain by the Fermeuse Formation.
Paleobiota
The Renews Head Formation is home to a small range of discoidal forms, like Aspidella, which have been noted to bear faint radial markings similar to Hiemalora. There are also unnamed Sphaeromorph Acritarchs known from this formation.''incertae sedis''
