OVERVIEW of the BEDROCK GEOLOGY of NORTHWEST IOWA by Brian J
Iowa DNR Geological Survey Bureau 109 Trowbridge Hall Iowa City IA 52252-1319 Phone: 319-335-1575 http://www.igsb.uiowa.edu OVERVIEW OF THE BEDROCK GEOLOGY OF NORTHWEST IOWA by Brian J. Witzke Iowa Department of Natural Resources Geological Survey Bureau May 1997 INTRODUCTION The region encompassed by the northwest Iowa bedrock geologic map includes the 19- county area generally north of latitude 42° 13’ N and west of longitude 93° 58’ W. Bedrock across most of the map area is mantled by a cover of Quaternary sediments, primarily glacial till, alluvium, and loess. The Quaternary cover typically ranges in thickness between about 100 to 400 feet (30 to 120 m) across most of the map area, and locally reaches thicknesses in excess of 500 feet (150 m) within the deeper parts of some bedrock channels. Bedrock exposure is limited to only scattered small areas in the map region. These include Cretaceous exposures scattered along the lower bluffs and adjacent tributaries of the Big Sioux and Missouri River Valleys in western Woodbury and Plymouth counties (e.g., Witzke and Ludvigson, 1987). Small areas of Cretaceous bedrock exposure are also noted at (1) Grant City, southeast Sac County, (2) Camp Quest near LeMars, Plymouth County, and (3) shale outcrop near the margin of the Manson Impact Structure along Lizard Creek in northwestern Webster County (Hartung and Anderson, 1996, p. 33). Significant exposures of Jurassic, Pennsylvanian, and Mississippian strata crop out in portions of the Des Moines River drainage of Webster and Humboldt counties. Economically important Mississippian limestone strata (Gilmore City Formation) are exposed near Gilmore City in eastern Pocahontas County (Woodson, 1989). -

It is now generally known that the youngest stages of trilobites found as fossils are minute ovate or discoid bodies, not more than one millimetre in length, in which the head por tion greatly predominates. Altogether they present very little likeness to the adult form, to which, however, they are trace able through a longer or shorter series of modifications. Since Barrande2 first demonstrated the metamorphoses of trilobites, in 1849, similar observations have been made upon a number of different genera by Ford,22 Walcott,34':*>':t6 Mat thew,28- 27' 28 Salter,32 Callaway,11' and the writer.4.5-7 The general facts in the ontogeny have thus become well estab lished and the main features of the larval form are fairly well understood. Before the recognition of the progressive transformation undergone by trilobites in their development, it was the cus tom to apply a name to each variation in the number of tho racic segments and in other features of the test. -
Ptychopariid Trilobites in the Middle Cambrian of Central Bohemia (Taxonomy, Biostratigraphy, Synecology)
Ptychopariid trilobites in the Middle Cambrian of Central Bohemia (taxonomy, biostratigraphy, synecology) VRATISLAV KORDULE A revision of ptychopariid trilobites from the Middle Cambrian of central Bohemia is presented. With a few exceptions, they were previously referred only to Ptychoparia striata. Three genera are recently distinguished: Ptychoparia Hawle & Corda, 1847, Ptychoparioides Růžička, 1940, and Mikaparia gen. nov. Seven species are described: three are revised, four are new, and two is left in open nomenclature; their stratigraphical ranges and significance are discussed. A new stratigraphical subdivision of the Middle Cambrian of the Skryje-Týřovice area is suggested, including three assemblage zones and three barren zones. Four substrate and bathymetrically controlled trilobite associations are recognized in the Skryje-Týřovice area. • Key words: Bohemia, Middle Cambrian, trilobites, new taxa, biostratigraphy.

MacFadden, President Elect, Paleontological Society Amy C. Henrici Since our last news, there is much to report from the Paleontological Society (PS). In Amateur Spotlight: particular, as you likely know, in 2016 the PS instituted a new avocational member George Martin category. Since that time, more than 60 members have signed up as avocational members; this bodes well for the future. The PS has also added a member of the Featured Organization: amateur/avocational community as an advisor Northwest Paleontological to the PS Council. We are pleased to announce Assocation that Jayson Kowinsky of the Pittsburgh, Pennsylvania area and founder of The Fossil Vertebrate Paleontology of Guy web site has agreed to serve a two-year Orange County, California term. Jayson is otherwise known to members of myFOSSIL in several capacities, including Scorpy, the Giant Sea as the first speaker in our 2016 webinar series, Scorpion! and as a presenter at GSA 2015 in South Carolina and 2016 in Pittsburgh, the latter WIPS’10th Founders where he also led a very successful field trip Symposium collecting Carboniferous plants. We are excited Jayson Kowinsky that Jayson has agreed to serve and we look Montbrook Otter forward to both his input and representation of the amateur fossil community.
