Mumbai: The second edition of the `Rocks, Minerals and Fossils Exhibition', which began here on Wednesday, will conclude on January 7.

The event, being held at the Convocation Hall of the University of Mumbai's Fort campus, is a joint effort between the Centre for Extra-Mural Studies of the University, the India Study Centre, the Deccan College Post Graduate and Research Institute, Pune and the Institute of Science, Mumbai.

The exhibition has brought together a unique collection of rocks, minerals and fossils. The minerals include a large number of beautiful crystalline geodes of Amethyst, Citrine, Cavansite, Vanadinite, Fluorite; polished balls of Agate, Carnelian, Onyx, Jasper and fossilised wood.

The fossils are divided into two groups, plant fossils and animal fossils. The plant fossils date from the Careboniferous (315 million years ago) to the Miocene (10 million years ago). These include dinosaur fossils and extinct mega shark teeth from the Triassic, Jurassic and Creataceous (250 to 65 million years ago) period.

The organisers are holding several activities for the casual visitors and students. These include a number of workshops on fossils, stone tool making, geology, gemology, minerals and a number of spot quizzes.
