    Coprolites.JPG

    From the album: MY FOSSIL Collection - Dpaul7

    Coprolites SITE LOCATION: Pungo River or Yorktown Formation, Aurora, Beaufort Co., North Carolina, USA TIME PERIOD: Miocene age (5.3-23 Million Years Ago) Data: A coprolite is fossilized feces. Coprolites are classified as trace fossils as opposed to body fossils, as they give evidence for the animal's behaviour (in this case, diet) rather than morphology. The name is derived from the Greek words (kopros, meaning "dung") and (lithos, meaning "stone"). They were first described by William Buckland in 1829. Prior to this they were known as "fossil fir cones" and "bezoar stones". They serve a valuable purpose in paleontology because they provide direct evidence of the predation and diet of extinct organisms. Coprolites may range in size from a few millimetres to over 60 centimetres. Coprolites, distinct from paleofaeces, are fossilized animal dung. Like other fossils, coprolites have had much of their original composition replaced by mineral deposits such as silicates and calcium carbonates. Paleofaeces, on the other hand, retain much of their original organic composition and can be reconstituted to determine their original chemical properties, though in practice the term coprolite is also used for ancient human faecal material in archaeological contexts. In the same context, there are the urolites, erosions caused by evacuation of liquid wastes and nonliquid urinary secretions.

    Dolphin Inner Ear Bone Fossil SITE LOCATION: Pungo River or Yorktown Formation, Aurora, Beaufort Co., North Carolina, USA TIME PERIOD: Miocene age (5.3-23 Million Years Ago) Data: Dolphins are a widely distributed and diverse group of aquatic mammals. They are an informal grouping within the order Cetacea, excluding whales and porpoises, so to zoologists the grouping is paraphyletic. The dolphins comprise the extant families Delphinidae (the oceanic dolphins), Platanistidae (the Indian river dolphins), Iniidae (the new world river dolphins), and Pontoporiidae (the brackish dolphins), and the extinct Lipotidae (baiji or Chinese river dolphin). There are 40 extant species of dolphins. Dolphins, alongside other cetaceans, belong to the clade Cetartiodactyla with even-toed ungulates. Cetaceans' closest living relatives are the hippopotamuses, having diverged about 40 million years ago. Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Cetartiodactyla

    Fossil Sea Urchin Spines SITE LOCATION: Pungo River or Yorktown Formation, Aurora, Beaufort Co., North Carolina, USA TIME PERIOD: Miocene age (5.3-23 Million Years Ago) Data: Sea urchins or urchins, archaically called sea hedgehogs, are small, spiny, globular animals that, with their close kin, such as sand dollars, constitute the class Echinoidea of the echinoderm phylum. Sea urchins have globe- to flattened-shaped bodies covered with spines. They are non-aggressive marine animals found all over the world. They live in shallow, rocky bottoms, or hide in sandy cervices. Human contact with sea urchins is either accidental or intentional. People accidentally step on them in shallow surf, or intentionally pick up the urchins, unaware that they must handle the spines with care to avoid injury. Sea urchins have two types of venomous organs - spines and pedicellaria. Spines produce puncture wounds. Pedicellaria are small, delicate seizing organs that lie between the spines and release venom when they attach to an object. A puncture injury from a sea urchin can cause swelling and redness around the area, which may lead to severe pain and infection. Multiple deep puncture wounds may cause fatigue, weakness, muscle aches, shock, paralysis, and respiratory failure. Death may occur. Kingdom: Animalia Phylum: Echinodermata Class: Echinoidea

    From the album: MY FOSSIL Collection - Dpaul7

    Conus Gastropod SITE LOCATION: James City Formation, North Carolina, USA TIME PERIOD: Miocene age (5.3-23 Million Years Ago) Data: Conus is a genus of predatory sea snails, or cone snails, marine gastropod mollusks in the family Conidae. Prior to 2009, cone snail species had all traditionally been grouped into the single genus Conus. However, Conus is now more precisely defined, and there are several other accepted genera of cone snails. For a list of the currently accepted genera, see Conidae. For a list of the currently accepted species within the genus Conus, based on the information in the World Register of Marine Species (WoRMS) list, see: list of Conus species. Species in the genus Conus sensu stricto can be found in the tropical and subtropical seas of the world, at depths ranging from the sublittoral to 1,000 m. They are very variable in some of their characters, such as the tuberculation of the spire and body whorl, striae, colors and the pattern of coloring. Many fossil species have been described; they are extensively distributed, and first appear in Cretaceous strata. Kingdom: Animalia Phylum: Mollusca Class: Gastropoda Family: Conidae Genus: Conus

    Fossil Marginella Gastropod a.JPG

    From the album: MY FOSSIL Collection - Dpaul7

    Fossil Marginella Gastropod SITE LOCATION: Pungo River or Yorktown Formation, Aurora, Beaufort Co., North Carolina, USA TIME PERIOD: Miocene age (5.3-23 Million Years Ago) Data: Marginella is a genus of small tropical and temperate sea snails, marine gastropod molluscs in the family Marginellidae, the margin snails. It is the type genus of the family. The shells of species in this genus are rounded, smooth and glossy, with a large aperture that appears to be toothed because it shows the edge of the columellar folds. In many species the shells are colorful. The glossy surface of the shell results from the fact that the mantle covers most of the shell when the animal is active. As is typical in the Neogastropoda, the animal has a long siphon. When the animal is active, the foot extends much further out than the edge of the shell. As is also typical for the Neogastropoda, species in this genus are carnivorous and predatory. Kingdom: Animalia Phylum: Mollusca Class: Gastropoda Family: Marginellidae Genus: Marginella

    Balanus sp. Barnacle Fossil SITE LOCATION: Pungo River or Yorktown Formation, Aurora, Beaufort Co., North Carolina, USA TIME PERIOD: Miocene age (5.3-23 Million Years Ago) Data: Balanus is a genus of barnacles in the family Balanidae of the subphylum Crustacea. This genus is known in the fossil record from the Jurassic to the Quaternary periods (age range: from 189.6 to 0.0 million years ago.). Fossil shells within this genus have been found all over the world. A barnacle is a type of arthropod constituting the infraclass Cirripedia in the subphylum Crustacea, and is hence related to crabs and lobsters. Barnacles are exclusively marine, and tend to live in shallow and tidal waters, typically in erosive settings. They are sessile (nonmotile) suspension feeders, and have two nektonic (active swimming) larval stages. Around 1,220 barnacle species are currently known. Kingdom: Animalia Phylum: Arthropoda Class: Maxillopoda Order: Sessilia Family: Balanidae Genus: Balanus

    From the album: MY FOSSIL Collection - Dpaul7

    Shark Vertebrae SITE LOCATION: Pungo River or Yorktown Formation, Aurora, Beaufort Co., North Carolina, USA TIME PERIOD: Miocene age (5.3-23 Million Years Ago) Data: Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays. However, the term "shark" has also been used for extinct members of the subclass Elasmobranchii outside the Selachimorpha, such as Cladoselache and Xenacanthus, as well as other Chondrichthyes such as the holocephalid eugenedontidans. Under this broader definition, the earliest known sharks date back to more than 420 million years ago. Kingdom: Animalia Phylum: Chordata Class: Chondrichthyes

    Fish Vertebrae a.JPG

    From the album: MY FOSSIL Collection - Dpaul7

    Fish Vertebrae SITE LOCATION: Pungo River or Yorktown Formation, Aurora, Beaufort Co., North Carolina, USA TIME PERIOD: Miocene age (5.3-23 Million Years Ago) Data: Fish are the gill-bearing aquatic craniate animals that lack limbs with digits. They form a sister group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well. However, traditionally fish are rendered paraphyletic by excluding the tetrapods (i.e., the amphibians, reptiles, birds and mammals which all descended from within the same ancestry). Because in this manner the term "fish" is defined negatively as a paraphyletic group, it is not considered a formal taxonomic grouping in systematic biology. The traditional term pisces (also ichthyes) is considered a typological, but not a phylogenetic classification. Kingdom: Animalia Phylum: Chordata Class: Osteichthyes

    Tetraodontidae (Puffer fish) gill plates SITE LOCATION: Pungo River or Yorktown Formation, Aurora, Beaufort Co., North Carolina, USA TIME PERIOD: Miocene age (5.3-23 Million Years Ago) Data: The Tetraodontidae are a family of primarily marine and estuarine fish of the order Tetraodontiformes. The family includes many familiar species which are variously called pufferfish, puffers, balloonfish, blowfish, blowies, bubblefish, globefish, swellfish, toadfish, toadies, honey toads, sugar toads, and sea squab. Pufferfishes and porcupinefishes share the order Tetraodontiformes with the triggerfishes, filefishes, boxfishes and their relatives. The tetraodontiforms (or plectognaths) include around 300 species from eight families. Though incredibly diverse, this broad group can be characterized as having modified scales that serve as plates or spines with resultantly restricted gill openings.

    Tetraodontidae (Puffer fish) gill plates SITE LOCATION: Pungo River or Yorktown Formation, Aurora, Beaufort Co., North Carolina, USA TIME PERIOD: Miocene age (5.3-23 Million Years Ago) Data: The Tetraodontidae are a family of primarily marine and estuarine fish of the order Tetraodontiformes. The family includes many familiar species which are variously called pufferfish, puffers, balloonfish, blowfish, blowies, bubblefish, globefish, swellfish, toadfish, toadies, honey toads, sugar toads, and sea squab. Pufferfishes and porcupinefishes share the order Tetraodontiformes with the triggerfishes, filefishes, boxfishes and their relatives. The tetraodontiforms (or plectognaths) include around 300 species from eight families.

    Chilomycterus (burrfish) mouth plate SITE LOCATION: Pungo River or Yorktown Formation, Aurora, Beaufort Co., North Carolina, USA TIME PERIOD: Miocene age (5.3-23 Million Years Ago) Data: Chilomycterus is a genus of diodontid tetraodontiform fishes commonly called "burrfish." The burrfish resembles the puffer in the positions of its dorsal and anal fins, but its skin is armed with short, stout, triangular spines instead of being merely prickly. These spines are sparsely scattered all over the trunk, with about 9 or 10 from nose to tail along any given line. Furthermore, the burrfish is oval in outline, not fusiform like the puffer; the openings of its nostrils are prolonged in a single tubular tentacle; its bony jaw plates are not divided by a median suture as they are in the puffer, hence each jaw apparently is armed with a single very broad incisor tooth instead of with two; the pectoral fins are not only much larger than in the puffer but their upper edge is level with the upper corner of the gill openings in the burrfish (considerable below it in the puffers); its eye is round, not oval; and its anal fin is below the dorsal, not behind the latter. We need only add that the soft dorsal and anal fins (it has no spiny dorsal) are both rounded, each has 10 to 12 rays; the caudal fin is very narrow and round-tipped; the pectorals are much broader than long, and there are no ventral fins.
