Until this time the earliest fossils had been found in rocks of the Cambrian era
and were a little over 600 million years old.
Although the Georgina Basin has not had a discovery to date, the location of the basin, and information from the limited exploration work conducted in the past, including 2D seismic data, suggest the presence of active Cambrian era
petroleum systems in the region with oil-mature source rocks and reservoirs occurring at shallow depths.
This ancient gene family probably first appeared in the genomes of sea-dwelling creatures prior to the Cambrian era
about 542-million years ago.
Researchers have claimed that the sandstone found at the mines in the region date back to about 600 million years, which would put the fossil in the Ediacaran age, just before the Cambrian era
that saw an explosion in the evolution of species.
At the time, Indian geologist Dr Rafat Azmi reported finding small, shell-like fossils, which were typical of those that date to the Cambrian era
about 500 to 600 million years ago.
