Overview of the family Deinotheriidae C.L. Bonaparte, 1841 [Mammalia, Proboscidea] with direction to fossil discoveries in Czech Republic.
Šmejkal, Roman ; Mazuch, Martin (advisor) ; Wagner, Jan (referee)
This work presents the family Deinotheriidae including the subfamily Chilgatherinae. Morphological differences of teeth point to anatomical differences between the genders Chilgatherium, Prodeinotherium and Deinotherium. Further, the anatomical differences of skull and postcranial skeleton of the Deinotherinae subfamily are described. The Extension of the family Deinotherium is tied to the migration routes from Africa to Asia and Europe. The Occurrence in the Czech Republic is confirmed by 2 important discovery sites. The first one is located in Horní Ves near Franzensbad where the skeleton of the species Prodeinotherium bavaricum was discovered. The second one is located near Česká Třebová and represented by the fragments of the lower jaw of the species Prodeinotherium cuvieri. The discussion focuses on the use of the lower tusks and the method of food intake.

Castorids (Castoridae, Mammalia) from the Early Miocene (MN 3) locality Ahníkov
Šmejkal, Roman ; Čermák, Stanislav (advisor) ; Mazuch, Martin (referee)
Beavers are members of Castoridae - the family of large rodents characterized by a robust skull of sciuromorphic type, a sciurognathous mandible, dentition with a tendency to hypsodoncy and incisives by uniserial microstructure. The aim of the thesis is a detailed morphometric analysis of the fossil material of beavers coming from the early Miocene (MN 3a) locality Ahníkov I, II in the Czech Republic. In the numerous material comprising 388 fragmentary specimens, all belonging to the genus Steneofiber, two distinct species were distinguished, attributed here as - Steneofiber eseri (the larger form) and Steneofiber aff. dehmi (the smaller form). Their taxonomy, systematics and assumed position within existing phylogenetic models were discussed. Key words: Castoridae, Steneofiber, Czech republic, Ahníkov, MN 3, early Miocene
