Triassic Period, Approx. 240 Million Years Old - Isalo Formation, Madagascar
Travel back 240 million years with this extraordinary Barasaurus fossil — a rare window into one of Earth’s earliest reptilian lineages, long before the rise of the dinosaurs. Discovered in Madagascar’s world-renowned Isalo formations, Barasaurus represents a crucial evolutionary stage in the early diversification of reptiles.
This remarkable specimen reveals itself in mirror image on both sides of the stone: when the rock was split, it exposed both the positive (raised fossil relief) and the negative (counterpart) impressions. Together, they form a captivating natural diptych — a perfect fossil pairing that captures the creature’s form in striking detail.
Highlights: • From the Triassic period — over 240 million years old • Discovered in Madagascar’s Isalo Formation • Rare “double” fossil showing both positive and negative impressions • Scientifically valuable and visually striking specimen • Dimensions (2 pieces): 46 × 32 cm
Condition: Authentic fossil — professionally prepared and preserved
