A majestic Brontosaurus, imagined as if carved from ancient, moss-covered stone, with sections of its colossal body glowing with an ethereal, soft amber light. Its massive, rounded form exhibits a weathered, coarse texture, interspersed with patches of vibrant green moss and delicate fern growth. The stone itself is a deep, variegated grey, suggesting immense age. Its long neck and tail taper gracefully, culminating in a broad, weighty tail tip.
