Notes on Preliminary Findings of Fossil Taxa

The quality of the holdings and conditions of loans have been already checked by Professor G. Arratia, who, using funds from one of her DFG (= German Science Foundation) grants visited Germans museums.  The visits have proved to be especially informative.  For instance, the quality of preservation of the material (complete and also disarticulated)  specimens will permit accurate morphological descriptions of numerous forms. Most of the material from some of the important Greman localities bearing cypriniforms are preserved as negatives.  However, no latex casts or peels have been produced.  Additionally,part of these materials are still unprepared.  Consequently, we expect to greatly increase the morpholgical information on many forms in this project, as a base to build up a list of characters used in phylogenetic anslyses of the whole order. (The contribution of DFG to visit different museums to check holdings is over  $1300).  Professor Meeman also examined significant holdings of fossil cypriniformes in China and southeastern Asia (in visiting other museums in Europe and USA) to establish the quality of specimens and determine materials for examination.  This museum travel has also been at her institutional expense.  PI Mayden has been working on the well preserved Miocene fossil species Notropis megalepis using CT scans (from Dr. Tim Rowe’s Digimorph Laboratory, UT Austin) and has developed composites of specimen scans taken from separate halves of the fossil.  These colorized fossil parts are „merged“ digitally to produce a complete specimen in a 3D animation for examination of important characters to be included in the overall analysis of morphological variation.  From this fossil very important characters are being extracted from most regions of the head and body.  You may examine the finished specimen at our Notropis megalepis site  or at the Digimorph Lab.

At the end of May, 2004, G. Arratia will attend an international meeting in Brazil, with the support of the DFG (German Science Foundation).  She has already arranged with the Museo de Ciencias Naturales in Cochabamba for her visit at the beginning of June.  She will revise the material described by Gayet in 1982 and, will check all possible related material (among recently collected specimens) and will arrange the corresponding loans.  (The contribution of DFG is about $3200).
