Cretaceous ammonite collection from Texas: R. Lasswitz, die Kreide-Ammoniten von Texas
Published online by Cambridge University Press: 20 May 2016
Extract
In 1904 R. Lasswitz described a collection of Cretaceous ammonites from Texas, most of which were collected in 1846 by Ferdinand Roemer. Apart from the historical value of the collection, Lasswitz described several new species, which also makes the collection important from a taxonomic point of view. According to Lasswitz, in his plate descriptions, all the original (figured) specimens of the (Roemer) collection were housed in the “Königlich Geologisches Museum” in Breslau. Adkins (1928) in his Handbook of Texas Cretaceous Fossils referred to the collection at “University of Breslau” and figured several specimens that he had photographed prior to 1928. He also made casts of some of the specimens (see, e.g., Young, 1979, p. 52).
