Sieht man von den mit einem Stern bezeichneten und auf Indien oder Centraiasien beschränkten Arten ab, so weisen die restlichen 17 und in Europa bekannten Species darauf hin, dass die Kreideschichten von Belutschistan dem oberen Obersenon, dem Maestrichtien, entsprechen. Ihre Fauna zeigt kaum Beziehungen zu denjenigen gleichalteriger Schichten Südindiens oder Nordafrikas, sehr enge dagegen zu der Südfrankreichs, so dass sie als zur europäischen Provinz gehörig angesehen werden kann. Sie lebte wahrscheinlich in der Nähe der östlichen Ufer der jüngeren Kreide- see. Wahrscheinlich trennte sie eine schmale Barre von der See, in welcher die obere Kreidefauna Südindiens lebte.

(Jour- nal international d' Anatomie et de Physiologie etc. 1896. 13. Fase. 9. 6 p. Taf. 16.) Hornbildungen von verhältnissmässig bedeutender Grösse sind beim Menschen ungemein selten. Kelsch führt 71 beobachtete Fälle an, in welchen die Hörner 35 mal auf dem Kopfe sassen. Eines der grössten solcher Hörner wird von Dubrand erwähnt : Dasselbe zeigte sich bei einer Frau von 51 Jahren und besass 21 cm Länge, 6 cm Umfang. Das von dem Verf. hier beschriebene und abgebildete Horn gehörte einer 65 Jahre alten Frau an; dasselbe hatte ungefähr 16 cm Länge und war ganz in derselben Weise gekrümmt, wie das Horn eines Widders. Die Veranlassung zu der Entstehung dieser Bildung gab eine eiternde Sackgeschwulst, auf deren Narbe sich später das Horn bildete. Zu erwähnen ist, dass die Frau noch zahlreiche andere solcher Geschwülste besass, und dass auch ihr Vater an solchen litt. Es handelt sich in diesem, wie in anderen Fällen natür- lich nur um eine localisirte Hypertrophie der Hornhaut der Epidermis. Verf. wirft aber die Frage auf, ob nicht in der Phylogenie der Säuger ähnliche durch Eiterung entstandene Reizzustände der Haut die erste Ver- anlassung gegeben haben könnten zu der Bildung von Hörnern, Geweihen, Stacheln, Panzern. [Bei Stacheln und Panzerplatten, welche reine Haut- Mammalia. -139- gebilde sind, mag' diese Frage sich einfach stellen. Schwieriger aber dürfte die Sache doch liegen bei Hörnern nnd Geweihen, wo gleichzeitig bezw. noch früher am Schädel die Bildung von Hornzapfen sich vollzog. Hier müsste man dann annehmen, dass der Reizzustand der Haut auch den darunterliegenden Knochen in Mitleidenschaft gezogen hätte. Ref.] Branco. Eug. Dubois et L. Manouvrier : Le „Pithecanthropus erectus" et l'origine de Thomm e. (Bull. d. 1. soc. d'Anthrop. de Paris. 1896. 460—467. 1 Textfig.) Der Vortrag ist im Ganzen nur eine Wiederholung des in der Berliner anthropologischen Gesellschaft gehaltenen und wurde seitdem in zahlreichen Zeitschriften veröffentlicht. Pühecanthropus nähert sich im Schädel- und Zahnbau den Anthropoiden, im Bau des Femur dagegen den Menschen ; er verbindet die Gattung Homo mit den Anthropoiden. Manouvrier stimmt dem Vortragenden bei. M. Schlosser. Nötling: On the occurrence of chipped (?) flints in the Upper Miocene of Burma. (Records of the Geolog. Survey of India. 27. 101.) Ein Conglomerat in der Gegend von Yenanyoung enthält nicht selten Reste von Säugethier en, und zwar von Arten der Siwalik-Fauna, darunter besonders häufig Hippotherium antüopinum und Bhinoceros perimense. Stellenweise kommen auch Brackwasserconchylien vor, die auf die einstige Anwesenheit eines Aestuarium schliessen lassen. Mit dieser Annahme lässt sich auch der Umstand, dass die Knochen sehr häufig abgerollt sind, sehr gut in Einklang bringen. Die untersten Lagen dieses Schichtencomplexes bestehen aus weichen Sandsteinen mit verkieseltem Holz und Knochen von Stegodon Clifti, Hippopotamus iravadicus und Krokodilen, darüber folgen braunröthliche Sandsteine mit Thonen und den erwähnten Conglomeraten, die von blauen Thonen und grauen, petroleumhaltigen Sandsteinen über- lagert werden. In den Conglomeraten fanden sich an einer Stelle einige Feuersteinsplitter, die z. Th. an bearbeitete Silex erinnern. Einer dieser Feuersteinsplitter lag dicht neben einem Hippothermm-Ztäm. An der Gleichalterigkeit dieser Silex mit den Conglomeraten, in denen sie vor- kommen, ist nun nicht im mindesten zu zweifeln. Sollten sie wirklich vom Menschen geformt sein, so hätten wir es hier mit den Spuren des pliocänen Menschen zu thun, doch gestattet sich Autor kein definitives Urtheil, eine Zurückhaltung, die durchaus anerkennenswerth erscheint.

  • The Bivalve Pholadomya Gigantea in the Early Cretaceous of Argentina: Taxonomy, Taphonomy and Paleogeographic Implications
    The bivalve Pholadomya gigantea in the Early Cretaceous of Argentina: Taxonomy, taphonomy and paleogeographic implications Darío G. Lazo Acta Palaeontologica Polonica 52 (2), 2007: 375-390 Pholadomya gigantea is a widely distributed Early Cretaceous bivalve mollusc. It has been recorded in the North Temperate, Tethyan, and South Temperate Realms. Based on recent field work and newly collected material from the Neuquén Basin, the taxonomy, mode of occurrence and palaeobiogeography of this species is reviewed. In the Agrio Formation (Valanginian-Barremian) P. gigantea is neither abundant nor dominant, but occurs throughout the unit. It was facies-dependent being restricted to well-oxygenated waters and soft to firm, sandy and bioclastic substrates of shoreface to inner shelf environments. The life habit of P. gigantea was similar to that of Recent Pholadomya candida , deep burrowing and sedentary, but it has not a pedal gape and accessory muscle scars related to valve closure. Thus a suspension-feeding habit, not a pedal-feeding system, may be inferred as is commonly suggested in other Jurassic and Cretaceous Pholadomya species. Pholadomya agrioensis is a valid taxon that is recorded in the Berriasian-Valanginian of Neuquén. It is similar in outline to P. gigantea and had probably the same basic palaeoecology, even though it has a blunt anterior margin, deep umbonal-ventral sulcus and distinct anterior ornamentation. Once in life position this species was capable of further digging in the sediment. This species probably burrowed in muddy substrates in the offshore zone. Pholadomya sanctaecrucis from the Valanginian of Europe and also recorded in Argentina is ornamented only with commarginal lines and should be removed to the genus Homomya.

Box 7458, Fort Smith, MT 59035 3P.O. Box 821, Cody, WY 82414 ____________________ ABSTRACT - Paleontological resources occur throughout the Paleozoic and Mesozoic formations exposed in Bighorn Canyon National Recreation Area. Isolated research on specific geologic units within Bighorn Canyon has yielded data on a wide diversity of fossil forms. A comprehensive paleonotological survey has not been previously undertaken at Bighorn Canyon. Preliminary paleontologic resource data is presented in this report as an effort to establish baseline data. ____________________ INTRODUCTION ighorn Canyon National Recreation Area (BICA) consists of approximately 120,000 acres within the Bighorn Mountains of north-central Wyoming and south-central Montana B (Figure 1). The northwestern trending Bighorn Mountains consist of over 9,000 feet of sedimentary rock. The predominantly marine and near shore sedimentary units range from the Cambrian through the Lower Cretaceous. Many of these formations are extremely fossiliferous. The Bighorn Mountains were uplifted during the Laramide Orogeny beginning approximately 70 million years ago. Large volumes of sediments, rich in early Tertiary paleontological resources, were deposited in the adjoining basins. This report provides a preliminary assessment of paleontological resources identified at Bighorn Canyon National Recreation Area. STRATIGRAPHY The stratigraphic record at Bighorn Canyon National Recreation Area extends from the Cambrian through the Cretaceous (Figure 2). The only time period during this interval that is not represented is the Silurian.

Asterozoans are free living, star-shaped echinoderms which are important components of benthic marine faunas worldwide. Their fossil record is, however, poor and fragmentary, probably due to dissarticulation of ossicles. In particular, fossil asteroids are infrequent in South America. A new species of starfish is reported from the early Valanginian of the Mulichinco Formation, Neuquén Basin, in the context of a shallow-water, storm-dominated shoreface environment. The specimen belongs to the Astropectinidae, and was assigned to a new species within the genus Tethyaster Sladen, T. antares sp. nov., characterized by a R:r ratio of 2.43:1, rectangular marginals wider in the interbrachial angles, infero- marginals (28 pairs along a median arc) with slightly convex profile and flat spines (one per ossicle in the interbrachials and two per ossicle in the arms).

  • The Mode of Life in the Genus Pholadomya As Inferred from the Fossil Record
    geosciences Article The Mode of Life in the Genus Pholadomya as Inferred from the Fossil Record Przemysław Sztajner Institute of Marine and Environmental Sciences, University of Szczecin, Mickiewicza 16A, 70-383 Szczecin, Poland; przemyslaw.sztajner@usz.edu.pl Received: 13 July 2020; Accepted: 21 September 2020; Published: 5 October 2020 Abstract: The paper is an attempt to reconstruct the mode of life of Pholadomya bivalves, very common in the fossil record, particularly that of the Jurassic. The only extant representative of the genus is extremely rare and very poorly known. Materials from the Polish Jurassic deposits (Bajocian–Kimmeridgian; Western Pomerania and Polish Jura) and literature data were used for the reconstruction. Specifically, observations on the anatomy, taphonomy, and diagenesis of the specimens examined as well as lithology of the deposits housing the specimens were used. Shell anatomy characteristics are known for their particular utility in mode of life reconstructions, although the extremely thin-shelled and coarsely sculpted bivalves, such as the Pholadomya examined, have not been studied so far. The reconstruction suggest a diversity of the mode of life, coincident with the morphological differences between the Pholadomya species. At least the adults of anteriorly flattened species are inferred to have lived extremely deeply buried in the sediment, and were hardly mobile. The smaller, more oval in shape, species were more mobile, and some of them are thought to have preferred life in shelters, should those be available. In addition, the function of the cruciform muscle, other than that considered so far, is suggested. Keywords: Pholadomya; Anomalodesmata; Bivalvia; life habit; deep burrowers; taphonomy; shell anatomy; cruciform muscle; Jurassic; Poland 1.

    BUI,I,ETINS OF AMERICAN PAI,EONTOI,OGY Vol. ao No. 70C Some Cretaceous and Tertiary Echinoids from Cuba By Norman E, Weisbord July 7, 1934 Paleontological Research Institution, Ithaca, NewYork U. S'. A. INTRODUCTION The echinoids described herewith were collected by the writer in the years 1931 to 1933 while engaged in a study of the geology of Cuba for The Atlantic Refining Company of Philadelphia. Permission to pu'blish this paper has been generously granted by this company through the intercession of Dr. Roy E. Dickerson, its chief geologist, to whom the writer is indebted for this and for his many helpful suggestions. The writer also wishes to express his appreciation to Professor G. D. Harris for the use of the facilities of the paleontological labratory of Cornell University and of the new-^born Paleonto- logical Research Institution, of which he is founder. The types of the new species described in this article are deposited in the Paleontological Research Institution at Ithaca, New York, in a fire-proof building recentlty constructed by Professor Harris. In this connection it might be well to state that most of the types of new species collected by the students of Professor Harris are to be deposited here where they can be properly cared for and safe from the hazards of fire. By express provision of the char- ter of the Institution, all collections contained therein may be studied by any bona-fide student of paleontology. Whenever any doubt exists in the identity of the Cuban spe- cies with those in other parts of the world, the writer has pre- ferred to call the Cuban species new, calling attention, however, to its similarity to the form with which it has been compared.

  • Turonian Bivalves from the Coastal Basin of Gabon, South of Libreville Les Bivalves Du Turonien Du Bassin Côtier Du Gabon, Sud De Libreville
    Bulletin de l’Institut Scientifique, Rabat, Section Sciences de la Terre, 2013, n° 35, 1–8. Turonian bivalves from the Coastal Basin of Gabon, South of Libreville Les bivalves du Turonien du bassin côtier du Gabon, Sud de Libreville Benjamin MUSAVU MOUSSAVOU*, Simplice Marin NDONG ONDO & Makaya M’VOUBOU Université des Sciences et Techniques de Masuku et URESTE, Faculté des Sciences, Département de Géologie, B.P. 913 Franceville, Gabon *(musavu@yahoo.fr). Abstract. The taxonomy and palaeo-ecology of the Turonian marine bivalve fauna from the geological section ‘Gabon Store’ (South of Libreville, Gabon) are here discussed. Seven species are recognized: Aphrodina angustosinuosa (Riedel), Aphrodina dutrugei (Coquand), Aphrodina sp., Granocardium productum (Sowerby), Lopha cf. lombardi (Dartevelle & Freneix), Pholadomya cf. adversa Riedel and Rastellum sp. The composition of the bivalve fauna and the sedimentary characteristics indicate a low-energy littoral paleo-environment at the ‘Gabon Store’ section. Two types of depositional environment are suggested: (1) an intertidal zone, represented by silty limestone and (2) a shallow subtidal zone, such as a bay or lagoon, represented by calcareous sandstone. Keywords: Turonian, bivalves, coastal basin, Libreville, Gabon. Résumé. La taxonomie et la paléoécologie de la faune des bivalves marins d’âge Turonien de la coupe de ‘Gabon Store’ (Sud de Libreville, Gabon) sont ici discutées.

  • Bivalve Pholadomya Gigantea in the Early Cretaceous of Argentina: Taxonomy, Taphonomy, and Paleogeographic Implications
    The bivalve Pholadomya gigantea in the Early Cretaceous of Argentina: Taxonomy, taphonomy, and paleogeographic implications DARÍO G. LAZO Lazo, D.G. 2007. The bivalve Pholadomya gigantea in the Early Cretaceous of Argentina: Taxonomy, taphonomy, and paleogeographic implications. Acta Palaeontologica Polonica 52 (2): 375–390. Pholadomya gigantea is a widely distributed Early Cretaceous bivalve mollusc. It has been recorded in the North Tem− perate, Tethyan, and South Temperate Realms. Based on recent field work and newly collected material from the Neuquén Basin, the taxonomy, mode of occurrence and palaeobiogeography of this species is reviewed. In the Agrio For− mation (Valanginian–Barremian) P. gigantea is neither abundant nor dominant, but occurs throughout the unit. It was fa− cies−dependent being restricted to well−oxygenated waters and soft to firm, sandy and bioclastic substrates of shoreface to inner shelf environments. The life habit of P. gigantea was similar to that of Recent Pholadomya candida, deep burrow− ing and sedentary, but it has not a pedal gape and accessory muscle scars related to valve closure. Thus a suspension−feed− ing habit, not a pedal−feeding system, may be inferred as is commonly suggested in other Jurassic and Cretaceous Pholadomya species. Pholadomya agrioensis is a valid taxon that is recorded in the Berriasian–Valanginian of Neuquén. It is similar in outline to P. gigantea and had probably the same basic palaeoecology, even though it has a blunt anterior margin, deep umbonal−ventral sulcus and distinct anterior ornamentation. Once in life position this species was capable of further digging in the sediment. This species probably burrowed in muddy substrates in the offshore zone.
