Pycnosteroides laevispinosusDescription: A rarely seen member of the Order Beryciformes, Family Pycnosteroididae, it is thought to have been a grazer on plants, much as the modern-day Tangs do. The genus died out during the Cretaceous, leaving no descendants. This one has exceptionally-preserved finnage, with even some musculature preserved. It is hard to believe that such a specimen is nearly 100 million years old!!
