This species belongs to a small order of marine ray-finned fishes, the Zeiformes. The order consists of about 40 species in six (or seven?) families, mostly deep-sea types: Zeidae (Dories), Parazenidae (Parazen), Zeniontidae, Oreosomatidae, Grammicolepidae, Cyttidae (?) and Caproidae (Boarfishes). Zeiformes are considered to be the sister taxon of a group making up the order Beryciformes and a huge conglomeration of spiny-rayed fishes known as the "percomorpha", including the Perciformes. They range in size from less than 5 cm to up to 90cm. Zeiformes are characterized by usually thin and deep, compressed, and oblong to disk-shaped bodies with 5 -10 soft rays and possibly a spine in the pelvic fins, 5 -10 dorsal fin spines and up to 4 anal fin spines. The upper jaw with minute, slender conical teeth is more or less protrusible. With their greatly compressed head and body, large mouth, and extremely protrusible upper jaw, the Zeiformes are successful ambush predators. They slowly approach an unsuspecting small fish by means of undulating waves of the transparent soft dorsal and anal fins. In one quick motion they drop the "trapdoor" lower jaw, shoot out the upper jaw, and expand the gill cavity, sucking in the hapless prey along with a considerable volume of water. Zeiform fishes are carnivores; they feed mainly on a variety of fishes but also consume cephalopods and crustaceans. This fish here is an Antigonia sp. from the menilith shales of Bircza in the Polish Carpathians. Antigonia sp. is a member of the family Caproidae (Boarfish, Capros = boar from the Greek kapros). Boarfish are small, with only a few species known to reach a maximum total length of 30 centimetres (12 in) and most reaching less than half that figure. All members of this order are characterized by a laterally compressed body that is as high as it is long. Boarfishes typically have three spines and 25 to 35 soft rays in the anal fin. The pectoral fins are rounded, the pelvic fins set below them (1 stout spine and 5 slightly softer finrays). The first dorsal fin consists of about nine to ten spines, the third being the longest and the strongest. The second dorsal fin consists out of 25 to 35 soft rays. The large eye is well suited to its habitat in deep marine waters ranging from 40m to 600m. The protractile mouth, forming a small tube when protruded, is perfect for catching small copepods, mysids, benthic crustaceans and worms. The living species are all characterized by red, pink or silvery coloration. Swidnicki, J. 1986.

Cordaites borassifolius plant Poland, Upper Silesia Carboniferous, Westphalian "C", Middle Pennsylvanian, Moscovian, (309.0 -305.9 million years ago) Dimension: matrix 65x65mm. Cordaites borassifolius was probably quite a large tree of monopodial or even sympodial stature. Its trunk diameter was at a minimum 0.5 m. Branches were between 1.1 m and spaced less than 0.7 m appart. The bases of the branches usually attained about 2/3 to 1/2 of the trunk width. The abaxial cuticle has stomata arranged in multiplex stomatal rows that formed a wide stomatiferous band. A transverse crypt above the stoma is an important diagnostic feature. The cordaitalean leaves, twigs, pith casts, fertile organs and seeds found are referable to a single natural species. The associated fertile organs belong to two types: 1) male fertile organs Florinanthus volkmannii and 2) a more robust, probably female, form similar to Cordaitanthus ovatus . Cuticles from the scales and long bracts of Florinanthus volkmannii have been studied in detail. Most scale cuticles are astomatal, but stomata may occur very rarely on some parts of the abaxial cuticle. Small trichomes grew from the scale margins. The cuticle of the bract has elongate cells and stomata are arranged in single stomatal rows on the abaxial cuticle. Many bilateral monosaccate pollen grains [ Florinites ovalis , Florinites guttatus and Pseudoillinites , with a central body bipolar attachment to the equatorial saccus were separated from scale surfaces of Florinanthus volkmannii . The pith cast belong to the species Artisia approximata . The seeds are small and of the " Cardiocarpus- type". Cordaites borassifolius grew in wet, peat-forming habitats and they were most likely trees of medium height.

Serranus Fossil Fish Poland Oligocene age (65.5 -23 million years ago) Serranus is a genus of fish in the family Serranidae. It is one of five genera known commonly as the "Atlantic dwarf sea basses". These fish are hermaphrodites, each individual possessing functional male and female reproductive tissues. When a pair spawns, one fish acts as a male and the other acts as a female. Kingdom: Animalia Phylum: Chordata Class: Actinopterygii Order: Perciformes Family: Serranidae Genus: Serranus-

Clupea and Paleogadus Fossil Fish Poland Oligocene age (65.5 -23 million years ago) Clupea is genus of planktivorous bony fish belonging to the family Clupeidae, commonly known as herrings. They are found in the shallow, temperate waters of the North Pacific and the North Atlantic oceans, including the Baltic Sea. Three species of Clupea are recognized. The main taxa, the Atlantic herring (Clupea harengus) and the Pacific herring (Clupea pallasii) may each be divided into subspecies. Herrings are forage fish moving in vast schools, coming in spring to the shores of Europe and America, where they form important commercial fisheries. Paleogadus was a codfish of the Oligocene.

This is a flint from Poland. Age: Malm/Cretaceous/Danian. What do you think? Reminds me of Neotrigonia or Pholadomya or a cardiid.
