ORNOPIA, Mark Jener V PaleoPM 201311287 I. Summarize (Tabulate) the biology, classification (items 24-28), morphology, paleontology, paleoecology and biostrat. ranges No. Taxonomic Classification Biology Morphology Palaeontology Paleoecology Biostratigraphic Range Other Description 1 Kingdom: Animalia Phylum: Cnidaria Class: Anthozoa Subclass: Hexacorallia Order: Rugosa A type of Solitary and Colonial form can bud asexually and may reproduce sexually Septum : Radial plate (from wall to axis of corallite) with 6 primary septa. Tabulae : transverse partitions Calyx : bowl-shaped depression or “seat” in which the living polyp resides Dissepiment : small curved plate in a corallite near the tabulae that is convex inward and upwards forming a vesicle Appearance: cone or horn-like Goniophyllum (Silurian) Calceola (Devonian) Phillipsastrea Caninia Dibunophyllum Palaeosmilia Zaphrentis Lonsdaleia Lithostrotion Marine sessile benthonic Live in shallow water; warm, well- oxygenated water with normal salinity (best in areas of slow deposition) Often found on reefs along with tabulate corals, stromatoporoids, brachiopods and bryozoans Ordovician-Permian Order Rugosa or also called “Tetracoralla” 2 Kingdom: Animalia Phylum : Cnidaria Class: Anthozoa Subclass: Hexacorallia Order: Tabulata A type of colonial form Skeleton : calcareous Epithica: lateral wall that separates each rather small corallite Tabula: transverse partitions and floor for polyp Septa: with radial partition typically small or absent, most common is 12 Appearance: honeycomb or chain-like Shape: flat to conical to spherical Carenipora Paleofavosites Propora (Ordovician) Favosites Halysites Heliolites Michelinia Syringopora reef builders in warm, shallow (less than 50m water depth), clear, well- oxygenated water; bottom free of silt. Ordovician-Permian Are extinct corals of anthozoans 3 Kingdom: Animalia Superphylum: Lophotrochozoa Phylum: Annelida Reproduction : normal sexually, hermaphroditic repetition of internal organs soft bodied Bilaterally symmetrical Annuli : ring-like constrictions, similar segments, and with segmentation of internal structures including nerves, muscles, circulatory, excretory and reproductive organs Septa: internal partition Burgessochaeta setigera Canadia spinose Myoscolex ateles Phragmochaeta Epifaunal benthos Early Ordovician-Recent Segmented worms: including earthworms (Oligochaeta), leeches (Hirudinea) and marine bristleworms (Polychaeta) 4 Kingdom: Animalia Phylum: Arthropoda Clade: Arachnomorpha Subphylum: Trilobitomorpha Class: Trilobita Reproduction: sexually Invertebrates with segmented bodies Exoskeleton: composed of calcite and calcium phosphate minerals in a lattice of chitin Cephalon: head Cephalic shield: single large plate.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
