Part I. Questions Reference Material GEO 2: Historical Geology with Lab Lab 6: Fossils and Time Name: ______________________________ Date: ___________ Part I. Questions Reference Material: What is meant by Phylogeny or Phylogenesis? How is this related to evolution? “The central ideas of evolution are that life has a history—it has changed over time—and that different species share common ancestors.” University of California Museum of Paleontology http://evolution.berkeley.edu/evolibrary/article/evo_01 The common taxonomic subdivisions in descending order (Kingdom, Phylum, Class, Order, Family, Genus, and Species). There are five kingdoms of organisms: 1. Animalia (animals) 2. Plantae (plants) 3. Monera (bacteria and blue‐green algae) – Includes Stromatolites 4. Fungi (mushrooms, fungus) 5. Protista (included in Rhizaria): single‐celled organisms, – Includes Foraminifera/Fusulinids, Diatoms, Radiolaria The Animal Kingdom animals can be grouped into the invertebrates (animals without backbones) and the vertebrates. There are more than 20 invertebrate Phyla, but the chief ones that are preserved as fossils include: 1. Phylum Porifera ‐ the sponges (may include Archeocyathids, or in a separate Phylum) 2. Phylum Cnidaria (formerly Coelenterata) ‐ the corals and jellyfish 3. Phylum Bryozoa ‐ the colonial moss animals 4. Phylum Brachiopoda ‐ the brachiopods or lamp shells 5. Phylum Arthropoda ‐ the insects, crabs, shrimp, lobsters, trilobites and eurypterids 6. Phylum Mollusca ‐ the clams (Bivalves), snails (Gastropods), octopus, squid, nautilus, and ammonites (Cephallopods) 7. Phylum Echinodermata ‐ the starfish, sand dollars, sea urchins, crinoids, and blastoids The vertebrates belong to Phylum Chordata (referring to the nerve chord that extends down the center of the spine). Our goal with lab is to be able to identify the following common fossils and provide a general age range: Porifera (sponges), Trilobites, Brachiopods, Bryozoans, Cnidaria (corral), Mollusca – including bivalves, ammonites, gastropods, Echinoderms – including crinoids, blastoids 1. Provide a short definition of a fossil 1 | Page GEO 2: Historical Geology with Lab Lab 6: Fossils and Time 2. Describe how the following processes of fossil preservation differ: Permineralization compared to Replacement 3. Briefly describe what is meant by a “trace fossil” 4. List the seven common taxonomic subdivisions (start with Kingdom) 5. What is meant by Phylogeny or phylogenesis? How is this related to evolution? From Poort and Carlson (Historical Geology Interpretations and Applications): Fossil animals and, less commonly fossil plants are used to determine the relative geologic age of a sediment; the nature of the paleoenvironments, and the characteristics of an ancient area. Certain fossils are especially useful for age determination. These fossils are known as Index Fossils. Index Fossils must fulfill the following conditions: 1. Organisms should have lived during a relatively short period of geologic time and should have been abundant. 2. Organisms should have had a wide geographical distribution that was not strongly influenced by facies changes 3. Organisms should have distinctive appearance to be easily recognized. 6. Consider the following collections of fossils. Use the age ranges of these fossils to answer the following questions. Specimen 1 – Ordovician‐Permian Specimen 2 – Silurian‐Mississippian Specimen 3 – Cambrian‐Triassic Specimen 4 – Devonian‐Eocene Specimen 5 – Ordovician‐Jurassic Specimen 6 – Mississippian‐Recent a. Which is the best index fossil? b. Which is the poorest index fossil? c. What combination of fossils is the most definitive? 2 | Page GEO 2: Historical Geology with Lab Lab 6: Fossils and Time 7. All of the fossils named in the column below are trilobites. The columns have been correlated based on rock type and fossils. Use the age ranges of the trilobite species to determine the geologic time interval corresponding to the Cherty Limestone. 3 | Page GEO 2: Historical Geology with Lab Lab 6: Fossils and Time Lab Activities Part 1 – Shape and Symmetry.

M. 5 | Page GEO 2: Historical Geology with Lab Lab 6: Fossils and Time Part 3 – Use the enclosed geologic range charts and Phyla information to answer the following questions. Be specific about class if different classes of phyla span different age ranges. 1. Which taxonomic group(s) were present during the Precambrian? 2. Which taxonomic groups were present during the Paleozoic Era? 3. Which taxonomic groups were abundant during the Mesozoic Era and which groups were either absent or had declined compared to the Paleozoic Era? 4. Which taxonomic groups were abundant during the Cenozoic Era and which groups were either absent or had declined compared to the Mesozoic Era? 5. Major extinctions occurred several times in the geologic past. What times of extinction are suggested by the geologic range information provide? Remember that not all members of a phylum go extinct during one of these events, but the total number of species may decline. 6. If you found a rock containing both Scleractinian corals and ammonoids, to which geologic periods might it belong? 6 | Page GEO 2: Historical Geology with Lab Lab 6: Fossils and Time Part 4 – Assign the following fossil assemblages to geologic age range (as specific as possible).

Corals have a hard calcareous skeleton, and may be solitary or colonial. Colonies are composed of many polyps living together. The "cup," in which an individual coral polyp sits, is called the Theca. Each theca is small (several millimeters to several centimeters in diameter), and roughly circular or hexagonal in shape. The theca is divided internally by vertical partitions called septae, arranged in a radial pattern. Types of corals are distinguished by presence or absence, and number of septae: The Paleozoic Rugose corals (or tetracorals) have septae arranged in multiples of four. The Mesozoic and Cenozoic Scleractinian corals (or hexacorals) have septae arranged in multiples of six. The Paleozoic Tabulate corals lack septae. Instead, they have horizontal plates within the theca called tabulae. Tabulae are one of the main features of the tabulate corals. Phylum Bryozoa ‐ Colonial (many microscopic individuals living physically united adjacent to one another). The individuals are called zooids, and they are housed in a hard "capsule" called a zooecium. The colony is called a zoarium. Individual zooecia (plural of zooecium) are very tiny (about the size of a pin‐hole, a millimeter or less in diameter). They are just large Bryozoans may be distinguished from corals enough to be seen with the unaided eye. The bryozoan because of the apertures in the skeleton are colony may resemble lace or a tiny net, may be much smaller. delicately branching, finger‐like, circular or dome‐ shaped. 8 | Page GEO 2: Historical Geology with Lab Lab

We compiled detailed information on 252 occurrences of belemnites in six National Park Service (NPS) areas in Alaska. This information was based on published literature and maps, unpublished U.S. Geological Survey internal fossil reports (“Examination and Report on Referred Fossils” or E&Rs), the U.S. Geological Survey Mesozoic locality register, the Alaska Paleontological Database, the NPS Paleontology Archives and our own records of belemnites found in museum collections. Few specimens have been identified and many consist of fragments. However, even these suboptimal specimens provide evidence that belemnites are present in given formations and provide direction for future research. Two especially interesting avenues for research concern the time range of belemnites in Alaska. Belemnites are known to have originated in what is now Europe in the Early Jurassic Hettangian and to have a well-documented world-wide distribution in the Early Jurassic Toarcian.

    Embryonic shell structure of Early–Middle Jurassic belemnites, and its significance for belemnite expansion and diversification in the Jurassic LARISA A. DOGUZHAEVA, ROBERT WEIS, DOMINIQUE DELSATE AND NINO MARIOTTI Doguzhaeva, L.A., Weis, R., Delsate, D. & Mariotti N. 2014: Embryonic shell structure of Early–Middle Jurassic belemnites, and its significance for belemnite expansion and diversification in the Jurassic. Lethaia, Vol. 47, pp. 49–65. Early Jurassic belemnites are of particular interest to the study of the evolution of skel- etal morphology in Lower Carboniferous to the uppermost Cretaceous belemnoids, because they signal the beginning of a global Jurassic–Cretaceous expansion and diver- sification of belemnitids. We investigated potentially relevant, to this evolutionary pat- tern, shell features of Sinemurian–Bajocian Nannobelus, Parapassaloteuthis, Holcobelus and Pachybelemnopsis from the Paris Basin. Our analysis of morphological, ultrastruc- tural and chemical traits of the earliest ontogenetic stages of the shell suggests that modified embryonic shell structure of Early–Middle Jurassic belemnites was a factor in their expansion and colonization of the pelagic zone and resulted in remarkable diversification of belemnites. Innovative traits of the embryonic shell of Sinemurian– Bajocian belemnites include: (1) an inorganic–organic primordial rostrum encapsulating the protoconch and the phragmocone, its non-biomineralized compo- nent, possibly chitin, is herein detected for the first time; (2) an organic rich closing membrane which was under formation. It was yet perforated and possessed a foramen; and (3) an organic rich pro-ostracum earlier documented in an embryonic shell of Pliensbachian Passaloteuthis. The inorganic–organic primordial rostrum tightly coat- ing the protoconch and phragmocone supposedly enhanced protection, without increase in shell weight, of the Early Jurassic belemnites against explosion in deep- water environment.

  • The Early Evolutionary History of Belemnites: New Data from Japan
    The Early Evolutionary History of Belemnites: New Data from Japan Yasuhiro Iba1*, Shin-ichi Sano2,Jo¨ rg Mutterlose3 1 Department of Natural History Sciences, Hokkaido University, Sapporo, Japan, 2 Fukui Prefectural Dinosaur Museum, Katsuyama, Japan, 3 Institute of Geology, Mineralogy and Geophysics, Ruhr-University Bochum, Bochum, Germany Abstract Belemnites (Order Belemnitida), a very successful group of Mesozoic coleoid cephalopods, dominated the world’s oceans throughout the Jurassic and Cretaceous. According to the current view, the phylogenetically earliest belemnites are known from the lowermost Jurassic (Hettangian, 201–199 Ma) of northern Europe. They are of low diversity and have small sized rostra without clear grooves. Their distribution is restricted to this area until the Pliensbachian (191–183 Ma). Here we describe two new belemnite taxa of the Suborder Belemnitina from the Sinemurian (199–191 Ma) of Japan: Nipponoteuthis katana gen et sp. nov., which represents the new family Nipponoteuthidae, and Eocylindroteuthis (?) yokoyamai sp. nov. This is the first reliable report of Sinemurian belemnites outside of Europe and the earliest record of typical forms of Belemnitina in the world. The Sinemurian belemnites from Japan have small to large rostra with one deep and long apical groove. Morphologically these forms are completely different from coeval European genera of Hettangian–Sinemurian age. These new findings suggest that three groups of Belemnitina existed in the Hettangian–Sinemurian: 1) European small forms, 2) Japanese very large forms, and 3) the typical forms with a distinctive apical groove, reported here. The Suborder Belemnitina therefore did not necessarily originate in the Hettangian of northern Europe. The new material from Japan documents that the suborder Belemnitina had a much higher diversity in the early Jurassic than previously thought, and it also shows strong endemisms from the Sinemurian onwards.

  • Specimens Sheds Light on the Structure of the Ammonite Brachial Crown C
    www.nature.com/scientificreports OPEN New evidence from exceptionally “well‑preserved” specimens sheds light on the structure of the ammonite brachial crown C. P. A. Smith1*, N. H. Landman2*, J. Bardin3 & I. Kruta2,3* Ammonite soft body remains are rarely preserved. One of the biggest enigmas is the morphology of the ammonite brachial crown that has, up till now, never been recovered. Recently, mysterious hook‑ like structures have been reported in multiple specimens of Scaphitidae, a large family of heteromorph Late Cretaceous ammonites. A previous examination of these structures revealed that they belong to the ammonites. Their nature, however, remained elusive. Here, we exploit tomographic data to study their arrangement in space in order to clarify this matter. After using topological data analyses and comparing their morphology, number, and distribution to other known cephalopod structures, in both extant and extinct taxa, we conclude that these hook‑like structures represent part of the brachial crown armature. Therefore, it appears that there are at least three independent evolutionary origins of hooks: in belemnoids, oegospids, and now in ammonites. Finally, we propose for the frst time a hypothetical reconstruction of an ammonite brachial crown. Ammonites are an abundant and iconic group of extinct marine organisms. Although they are ubiquitous in the fossil record, the anatomy of their sof body is unfortunately very poorly known, hindering our knowledge of their paleoecology and paleobiology. One of the biggest uncertainties involves the morphology of their brachial crown. According to phylogenetic bracketing, it is generally assumed that they had ten arms1,2. However, no remains of arms or arm structures have ever been discovered in ammonites, not even when internal organs are preserved3.

  • Absence of Suction Feeding Ichthyosaurs and Its Implications for Triassic Mesopelagic Paleoecology
    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2013 Absence of Suction Feeding Ichthyosaurs and Its Implications for Triassic Mesopelagic Paleoecology Motani, Ryosuke ; Ji, Cheng ; Tomita, Taketeru ; Kelley, Neil ; Maxwell, Erin ; Jiang, Da-yong ; Sander, Paul Martin Abstract: Mesozoic marine reptiles and modern marine mammals are often considered ecological analogs, but the extent of their similarity is largely unknown. Particularly important is the presence/absence of deep-diving suction feeders among Mesozoic marine reptiles because this would indicate the establish- ment of mesopelagic cephalopod and fish communities in the Mesozoic. A recent study suggested that diverse suction feeders, resembling the extant beaked whales, evolved among ichthyosaurs in the Triassic. However, this hypothesis has not been tested quantitatively. We examined four osteological features of jawed vertebrates that are closely linked to the mechanism of suction feeding, namely hyoid cor- pus ossification/calcification, hyobranchial apparatus robustness, mandibular bluntness, and mandibular pressure concentration index. Measurements were taken from 18 species of Triassic and Early Jurassic ichthyosaurs, including the presumed suction feeders. Statistical comparisons with extant sharks and marine mammals of known diets suggest that ichthyosaurian hyobranchial bones are significantly more slender than in suction-feeding sharks or cetaceans but similar to those of ram-feeding sharks. Most importantly, an ossified hyoid corpus to which hyoid retractor muscles attach is unknown in all butone ichthyosaur, whereas a strong integration of the ossified corpus and cornua of the hyobranchial apparatus has been identified in the literature as an important feature of suction feeders.

Coleoids are characterized by internal shell (endocochleate), ink sac and arm hooks, while nautilids lack an ink sac, arm hooks, suckers, and have an external conch (ectocochleate). Differentiating between straight conical conchs (orthocones) of Palaeozoic Coleoidea and other ectocochleates is only possible when rostrum (shell covering the chambered phragmocone) and body chamber are preserved. Here, we provide information on how this internalization might have evolved. We re-examined one of the oldest coleoids, Gordoniconus beargulchensis from the Early Carboniferous of the Bear Gulch Fossil- Lagerstätte (Montana) by synchrotron, various lights and Reflectance Transformation Imaging (RTI). This revealed previously unappreciated anatomical details, on which we base evolutionary scenarios of how the internalization and other evolutionary steps in early coleoid evolution proceeded. We suggest that conch internalization happened rather suddenly including early growth stages while the ink sac evolved slightly later.
