This nodule from the early Triassic of Madagascar contains a very detailed fossil shrimp known as Ambilobeia karojoi. Notice the incredible detail preserved here, remarkable for a specimen nearly a quarter of a billion years old. What is even more remarkable about nodules from the region is that unlike most nodules that are part/counterpart examples, this one is a natural mold, preserving the details with remarkable fidelity. Details like large claws, head and rostrum and tail are easly visible. Well centered and complete. Shrimp are differentiated from the similar prawns by the structure of their gills, and by the fact that female shrimp (like all pleocyemates) brood the eggs on their pleopods (swimming ) legs. Preserved on a 7 x 5 cm matrix. Found in Ambilobe, Madagascar Triassic Rare and beautiful preservation Concretion is glued. Plastic display included
