Email: [email protected] ARTICLE INFO ABSTRACT Article history: We review the initial development of Bacterial Paleontology in Mongolia and Received 10 September 2019 present some electron microscopic images of fossil bacteria in different stages of Accepted 9 October 2019 preservation in sedimentary rocks. Indeed bacterial paleontology is one the youngest branches of paleontology. It has began in the end of 20th century and has developed rapidly in recent years. The main tasks of bacterial paleontology are detailed investigation of fossil microorganisms, in particular their morphology and sizes, conditions of burial and products of habitation that are reflected in lithological and geochemical features of rocks. Bacterial paleontology deals with fossil materials and is useful in analysis of the genesis of sedimentary rocks, and sedimentary mineral resources including oil and gas. The traditional paleontology is especially significant for evolution theory, biostratigraphy, biogeography and paleoecology; however bacterial paleontology is an essential first of all for sedimentology and for theories sedimentary ore genesis or biometallogeny Keywords: microfossils, phosphorite, sedimentary rocks, lagerstatten, biometallogeny INTRODUCTION all the microorganisms had lived and propagated Bacteria or microbes preserved well as fossils in without breakdowns. Bacterial paleontological various rocks, especially in sedimentary rocks data accompanied by the data on the first origin alike natural substances. -
Skeletonized Microfossils from the Lower–Middle Cambrian Transition of the Cantabrian Mountains, Northern Spain
Skeletonized microfossils from the Lower–Middle Cambrian transition of the Cantabrian Mountains, northern Spain SÉBASTIEN CLAUSEN and J. JAVIER ÁLVARO Clausen, S. and Álvaro, J.J. 2006. Skeletonized microfossils from the Lower–Middle Cambrian transition of the Cantabrian Mountains, northern Spain. Acta Palaeontologica Polonica 51 (2): 223–238. Two different assemblages of skeletonized microfossils are recorded in bioclastic shoals that cross the Lower–Middle Cambrian boundary in the Esla nappe, Cantabrian Mountains. The uppermost Lower Cambrian sedimentary rocks repre− sent a ramp with ooid−bioclastic shoals that allowed development of protected archaeocyathan−microbial reefs. The shoals yield abundant debris of tube−shelled microfossils, such as hyoliths and hyolithelminths (Torellella), and trilobites. The overlying erosive unconformity marks the disappearance of archaeocyaths and the Iberian Lower–Middle Cambrian boundary. A different assemblage occurs in the overlying glauconitic limestone associated with development of widespread low−relief bioclastic shoals. Their lowermost part is rich in hyoliths, hexactinellid, and heteractinid sponge spicules (Eiffelia), chancelloriid sclerites (at least six form species of Allonnia, Archiasterella, and Chancelloria), cambroclaves (Parazhijinites), probable eoconchariids (Cantabria labyrinthica gen. et sp. nov.), sclerites of uncertain af− finity (Holoplicatella margarita gen. et sp. nov.), echinoderm ossicles and trilobites. Although both bioclastic shoal com− plexes represent similar high−energy conditions, the unconformity at the Lower–Middle Cambrian boundary marks a drastic replacement of microfossil assemblages. This change may represent a real community replacement from hyolithelminth−phosphatic tubular shells to CES (chancelloriid−echinoderm−sponge) meadows. This replacement coin− cides with the immigration event based on trilobites previously reported across the boundary, although the partial infor− mation available from originally carbonate skeletons is also affected by taphonomic bias. -

The Cambrian Explosion: a Big Bang in the Evolution of Animals
The Cambrian Explosion A Big Bang in the Evolution of Animals Very suddenly, and at about the same horizon the world over, life showed up in the rocks with a bang. For most of Earth’s early history, there simply was no fossil record. Only recently have we come to discover otherwise: Life is virtually as old as the planet itself, and even the most ancient sedimentary rocks have yielded fossilized remains of primitive forms of life. NILES ELDREDGE, LIFE PULSE, EPISODES FROM THE STORY OF THE FOSSIL RECORD The Cambrian Explosion: A Big Bang in the Evolution of Animals Our home planet coalesced into a sphere about four-and-a-half-billion years ago, acquired water and carbon about four billion years ago, and less than a billion years later, according to microscopic fossils, organic cells began to show up in that inert matter. Single-celled life had begun. Single cells dominated life on the planet for billions of years before multicellular animals appeared. Fossils from 635,000 million years ago reveal fats that today are only produced by sponges. These biomarkers may be the earliest evidence of multi-cellular animals. Soon after we can see the shadowy impressions of more complex fans and jellies and things with no names that show that animal life was in an experimental phase (called the Ediacran period). Then suddenly, in the relatively short span of about twenty million years (given the usual pace of geologic time), life exploded in a radiation of abundance and diversity that contained the body plans of almost all the animals we know today. -

Robison1 1University of Kansas, Department of Geology, Lawrence, Kansas 66045, USA, [email protected], [email protected]; 2Sinclair Oil & Gas Company, Salt Lake City, Utah 84130, USA, [email protected] ABSTRACT Emeraldella is a rare arthropod of relatively large body size that belongs with the trilobite-like arthropods, Artiopoda. E. brutoni n. sp. from the Wheeler Formation of west-central Utah is the second species described and marks the first confirmed occurrence of Emeraldella outside the Burgess Shale of British Columbia. An articulated, flagelliform telson, similar to that of the Burgess Shale taxon Molaria, is recognized in Emeraldella. Evidence for the presence of lamellae on the exopods of Molaria is presented, supporting affinity of that taxon with Artiopoda. A close relationship between Emeraldella and Molaria is tentatively suggested, based on the morphology of tergites and telson. Keywords: Wheeler Formation, Drum Mountains, exceptional preservation, Arthropoda INTRODUCTION others (2007), Elrick and Hinnov (2007), Brett and others (2009), Halgedahl and others (2009), and Howley and Jiang (2010), The Wheeler Formation of west-central Utah is well known have provided more detailed information about its stratigraphy for its diverse and exceptionally preserved biota, which was and depositional environments.

Detection of Biosignatures in Million Years Old Fossils with the “Standoff Bio- Finder”
49th Lunar and Planetary Science Conference 2018 (LPI Contrib. No. 2083) 2777.pdf DETECTION OF BIOSIGNATURES IN MILLION YEARS OLD FOSSILS WITH THE “STANDOFF BIO- FINDER”. T. E. Acosta-Maeda1, A. K. Misra1, M. Sandford1, S. K. Sharma1, D. Garmire2, and J. Porter1, 1Hawaiʻi Institute of Geophysics and Planetology, Univ. of Hawaiʻi at Mānoa, 1680 East-West Rd, Honolulu, Hawaiʻi, USA, 96822; 2Department of Electrical Engineering, Univ. of Hawaiʻi at Mānoa, Honolulu, HI 96822. [email protected]. Introduction: The “Standard Biofinder” has been developed at the University of Hawaiʻi with the intent of quickly locating biological materials in wide geolog- ical contexts in planetary exploration [1]. The Standoff Biofinder locates bio-fluorescent materials by taking live images that highlight the short lifetime fluorescence emitting objects [2]. Since its creation [3-5], the instru- ment has been proven to distinguish between mineral and biogenic fluorescence, work from standoff dis- tances (1-10 m) in daylight conditions with short meas- urement times (0.1s), and to differentiate between dif- ferent biogenic materials by taking color images. These capabilities could help an exploration rover identify ob- jects of interest for the ‘search for life’ beyond Earth and then dedicate other characterization techniques, such as Raman or LIBS, to determine the molecular and ele- mental composition of the selected targets. For this work, we used the “Color Biofinder” version of the in- strument [5] in combination with time-resolved fluores- cence measurements to assess its capabilities to detect and characterize fossils as biosignatures. Fossils are pre- served remains from biological entities from past geo- logical ages.
