This remarkable plaque displays the remains of nine distinct specimens of the extinct spiny sea urchin named for the locale of their discovery, in Brownwood Lake Spillway, West Texas. Each is like a starburst of delicate barbed spines from the small central body and together they create a dynamic and arresting group in the natural matrix measuring 16 x 15 inches.
