Devonian Bryozoans of the Holy Cross Mountains, Poland
ACT A PAL A EON T 0 LOG ICA POLONICA Vol. XVIII 1973 No.4 MARIA KIEPURA DEVONIAN BRYOZOANS OF THE HOLY CROSS MOUNTAINS, POLAND. PART II. CYCLOSTOMATA AND CYSTOPORATA Abstract. - Descriptions are given of 33, species of Middle Devonian Bryozoa from the Holy Cross Mts., belonging to the orders Cyclostomata and Cystoporata. Cyclo stomata are represented by 26 species (4 new: Corynotrypa (Corynotrypa) skalensis, C. (C.) basiplata, Stomatopora varigemmata and Diversipora bitubulata n. gen.). Cystoporata are represented by 7 new species: Ceramoporella orbiculata, C. grandi cystica, Favositella integrimuralis, Fistulipora boardmani, F. emphantica, Cyclotrypa nekhoroshevi and Fistuliramus astrovae. The systematic assignment of the genus Hederella Hall, 1881 has been discussed and the "tabulate-like" microstructure of the zooecial walls of this genus examined. In addition, the epifauna and associated assemblages have been characterized as well as the geological and palaeoecological conditions in which the described Bryozoa occurred. INTRODUCTION Among the Middle Devonian Bryozoa of the Holy Cross Mts., the present author has, up to now, described Ctenostomata (Kiepura, 1965). The present paper is a continuation of her investigations on the Middle Devonian Bryozoa of this region and contains descriptions of 33 species belonging to 9 genera of the orders Cyclostomata and Cystoporata occur ring in the Grzegorzowice - Skaly profile. The bryozoan collection of the Palaeozoological Institute of the Polish Academy of Sciences also contains a rich material representing the orders Trepostomata and Cryptostomata from the Middle Devonian of the Holy Cross Mts., which will be described at a future date. The material described in the present paper was collected by the author during several years of fieldwork (1950-1954). -
UPPER DEVONIAN CONODONTS ASSOCIATED with a LARGE PLACODERM FISH SKULL from the CANNING BASIN, WESTERN... Download
Rec. West. Aust. Mus. 1987,13 (4): 501-513 Upper Devonian conodonts associated with a large placoderm fish skull from the Canning Basin, Western Australia John A. Long* Abstract Conodonts retrieved from limestone encasing the skull of a large placoderm fish, from an unknown lo'cation in the south-eastern Canning Basin, indicate an age of mid-Famennian (toIIB) because of the concurrent presence of the following taxa: Nothognathella palmatiformis, Nothognathella sp. nov, A. Druce 1976,Palmatolepis glabra pectinata, P. quadrantinodosa inflexa, P. quadrantinodosa inflexoidea, P. marginifera s.s., Polygnathus triphyllatus, P. glaber s.s. and P. germanus s.s. The assemblage represents a palmatolepid-polygnathid biofacies dominated by palmatolepids, and is typical of muddy outer shelf to sandy inner shelf environ ments. The occurrence of certain taxa which have only been previously recorded in the Canning Basin from the Virgin Hills Formation, together with the lithology of the specimen, and palaeoecological information afforded by the conodonts, suggests that the specimen was derived from the uppermost section of the Virgin Hills Formation. Introduction A large dinichthyid placoderm fish skull has recently been described as a new genus, Westralichthys Long (1987) even though the exact location and lithological source of the specimen is unknown. A limited conodont fauna of 76 elements was recovered from dilute acetic acid preparation of the dinichthyid skull. The fauna contains a number of age diagnostic species which have been used to narrow the possible age and stratigraphic source of the specimen. It is significant that the conodonts indicate a much younger age for the skull than the well known lower Frasnian Gogo fish fauna (Gardiner and Miles 1975), also from the same region. -

Fossil Microbial Shark Tooth Decay Documents in Situ Metabolism Of
www.nature.com/scientificreports OPEN Fossil microbial shark tooth decay documents in situ metabolism of enameloid proteins as nutrition source in deep water environments Iris Feichtinger1*, Alexander Lukeneder1, Dan Topa2, Jürgen Kriwet3*, Eugen Libowitzky4 & Frances Westall5 Alteration of organic remains during the transition from the bio- to lithosphere is afected strongly by biotic processes of microbes infuencing the potential of dead matter to become fossilized or vanish ultimately. If fossilized, bones, cartilage, and tooth dentine often display traces of bioerosion caused by destructive microbes. The causal agents, however, usually remain ambiguous. Here we present a new type of tissue alteration in fossil deep-sea shark teeth with in situ preservation of the responsible organisms embedded in a delicate flmy substance identifed as extrapolymeric matter. The invading microorganisms are arranged in nest- or chain-like patterns between fuorapatite bundles of the superfcial enameloid. Chemical analysis of the bacteriomorph structures indicates replacement by a phyllosilicate, which enabled in situ preservation. Our results imply that bacteria invaded the hypermineralized tissue for harvesting intra-crystalline bound organic matter, which provided nutrient supply in a nutrient depleted deep-marine environment they inhabited. We document here for the frst time in situ bacteria preservation in tooth enameloid, one of the hardest mineralized tissues developed by animals. This unambiguously verifes that microbes also colonize highly mineralized dental capping tissues with only minor organic content when nutrients are scarce as in deep-marine environments. Teeth and bones are ofen the only evidence of ancient vertebrate life because of the mineralized nature of tissues. Tere are numerous possibilities for chemical alteration during the transition from the bio- to the lithosphere of which bacterial catabolysis of these tissues and organic matter within the carcass is an important example 1,2. -

A BIBLIOGRAPHY OF THE CONODONTS WITH DE- SCRIPTIONS OF EARLY MISSISSIPPIAN SPECIES By Grace B. Holmes Of the Eastern High School, Washington, D. C. INTRODUCTION The present contributions to the study of the conodonts was pre- pared at the suggestion of Dr. R. S. Bassler and under his direction in the paleontological laboratory of the United States National Museum where extensive collections of these toothlike structures were avail- able. As Doctors Ulrich and Bassler had just completed their paper on the classification of the conodonts and had applied their new classification in the description of an Upper Devonian fauna of western New York and an early Mississippian one from Tennessee, it was thought best that my work should carry these studies to the Mississippian rocks of Alabama and also include for the ready refer- ence by students illustrations of previously described species, with exception of three publications, and a bibliography of the group. The exceptions mentioned refer to the work of Bryant in 1921, Ulrich and Bassler in 1926, and Roundy in 1926, copies of which are still available to the student. ZOOLOGICAL AFFINITIES OF THE CONODONTS The affinities of the conodonts have been a subject of controversy almost since their discovery by Pander in 1856. That there was no doubt in Pander's mind as to their relationship may be ascertained from the title of his monograph. He studied the internal as well as the external structure of the fossils and saw in their formation fishlike characters somewhat of the Selachian type. The question concerning the affinities of these fossils seems to have had its birth in the mind of Dr. -

Thomas and Balster: Micropaleontological Zones in Iowa Micropaleontological Zones in Iowa By L. A. THOMAS and C. A. BALSTER Micropaleontological studies in the Iowa geologic section have been gaining impetus in the past few years, but no previous attempt has been made to assemble the accumulated information. The value of microfossils in defining and correlating stratigraphic units is generally accepted. This paper is a compilation of existing in formation in an attempt to establish preliminary fauna! zones. Where diagnostic fossils for the various zones were not indicated by the original author we have chosen them according to relative abundance and unique occurrence, if possible. In some instances inadequate data limit the application of this method, and require listing of a larger part of the assemblage than would otherwise be necessary.
