Description
| - The Upper Cretaceous (Cenomanian through Campanian) sedimentary rocks of Southern Utah in the USA yielded, during the past 15 years, a great number of disarticulated skeletal remains of small vertebrates, including frogs. The mentioned stratigraphic sequence represents a nearly uninterrupted sequence of strata deposited during almost 30 million years, in a relatively restricted geographic area. Abundance of fossil anuran remains is comparatively high in washing samples, and although traditional separation techniques (i.e., screen washing of matrix) caused partial destruction of the fragile anuran bones, the amount and kind of preserved bones make their sufficiently precise taxonomic determination possible. Preliminary analysis of the material recovered until now suggests that anuran samples from various localities represent taxonomically diversified assemblages that can be compared with each other not only in geographical, but in geochronological context as well. Anurans from the Late Cretaceous of (en)

| - Studiem fosilních kostí žab ze 36 lokalit svrchní křídy jižního Utahu, reprezentující období téměř 25 mil. let se zjistilo, že se zvyšovalo zastoupení větších forem, jejich amficélní obratel již postrádal chordami kanál, a že taxonomická diverzita na některých lokalitách byla poměrně vysoká.

- Investigation of fossil bones from 36 Late Cretaceous localities of south Utah, representing the period of about 25 Mya, revealed that the percentage of larger taxa increased, their amphicoelous vertebra lacked the notochordal canal, and taxonomie diversity in some localities was rather high.
