Současný pohled na evoluci chobotnatců Současná systematika chobotnatců není kompletně odvozena od jejich fylogeneze, rekonstruované pomocí kladistických metod. Diskutované skupiny tak mnohdy nepředstavují monofyletické skupiny. Přestože jsou taxonomické kategorie matoucí (např. Laurin 2005), jsem do jisté míry nucen je používat. Některým skupinám úrovně stále přiřazeny nebyly a zde této skutečnosti není přisuzován žádný význam. V této rešerši jsem se zaměřil hlavně na poznatky, které následovaly po vydání knihy; The Proboscidea: Evolution and Paleoecology of Elephants and Their Relatives, od Shoshaniho a Tassyho (1996). Chobotnatci jsou součástí skupiny Tethytheria společně s anthracobunidy, sirénami a desmostylidy (Shoshani 1998; Shoshani & Tassy 1996; 2005; Gheerbrant & Tassy 2009). Základní klasifikace sestává ze dvou skupin. Ze skupiny Plesielephantiformes, do které patří čeledě Numidotheriidae, Barytheriidae a Deinotheridae a ze skupiny Elephantiformes, do které patří čeledě Palaeomastodontidae, Phiomiidae, Mammutida, Gomphotheriidae, tetralofodontní gomfotéria, Stegodontidae a Elephantidae (Shoshani & Marchant 2001; Shoshani & Tassy 2005; Gheerbrant & Tassy 2009). -

A PRELIMINARY REPORT By ERWIN HINCKLEY BARBOUR The subfamily of longirostrine mastodonts known as the Amebelodontinae have been so recently discovered and described that as yet theY; are little known by the citizens of this state. They are most briefly and directly described as shovel-tusked mastodons. The first one found, namely Amebelodon fricki, was secured in April 1927, and was pub lished June 1927. In the meantime, many other examples of Amebelodonts have been added to the Morrill Palaeon tological Collections of the Nebraska State Museum.

The Distribution of Proboscidea (Elephants) Professor Dr
The Distribution of Proboscidea (Elephants) Professor Dr. Erich Thenius [In: Kosmos #5, May, pp. 235-242, 1964, Stuttgart] When I speak here about animals with a trunk, I do not mean the tapirs or pigs, but I refer only to the elephants and their ancestors, like the Mastodons and Dinotheria which we call the Proboscidea (after the Greek: proboscis = trunk). Their main characteristic is their remarkable trunk which has been fashioned to become a “gripping” organ. That organ was not present in the geologically oldest ancestors whose skeletons stem from the deposits of the Eocene (old Tertiary) in Africa. Even though we have no “soft tissues” of those animals, their skeletal features suffice to tell the scientist just what their bodily characteristics would have been. Thus also, we are not really going to discuss much about their distribution in historic times, but rather, we will concentrate on the development of these characteristic mammals, from their inception to their distribution in the past. A history of the Proboscidea is necessarily a history of their distribution in time and space. Information of these animals is available from numerous fossil findings in nearly all continents. But, before we even consider the fossil history, let us take a quick look of the current distribution of elephants which is shown in Figure 1. Nowadays, there are only two species of elephants: the Indian and African elephants. They not only differ geographically but also morphologically. That is to say, they are different in their bodily form and in their anatomy in several characteristics as every attentive zoo visitor who sees them side-by-side easily observes: The small-eared Indian elephant (Elephas maximus) has a markedly bowed upper skull; the African cousin (Loxodonta africana) has longer legs and markedly larger ears. -

New Mexico Museum of Natural History and Science Bulletin 44. 239 MAGNETIC STRATIGRAPHY OF THE MASSACRE LAKE BEDS (LATE HEMINGFORDIAN, EARLY MIOCENE), NORTHWEST NEVADA, AND THE AGE OF THE “PROBOSCIDEAN DATUM” IN NORTH AMERICA DONALD R. PROTHERO1, EDWARD BYRD DAVIS2 AND SAMANTHA S.B. HOPKINS2 1 Department of Geology, Occidental College, Los Angeles, CA 90041; 2 Department of Geological Sciences, University of Oregon, Eugene, OR 97403 Abstract—The “Proboscidean Datum” was proposed by Tedford et al. (1987) and Woodburne and Swisher (1995) as a marker of the late Barstovian (middle Miocene, about 14.5 Ma) in North America. Subsequently, a number of pre-late Barstovian proboscidean fossils have been reported, casting doubt on the validity of the Proboscidean Datum. The oldest of these is from the late Hemingfordian Massacre Lake local fauna of northwest Nevada, which produced a single proboscidean tooth fragment. Magnetic stratigraphy was conducted on these beds, which yielded a stable remanence held mainly in magnetite that was entirely reversed in polarity. Based on the 40Ar/39Ar date of 16.474 ±0.035 Ma at the top of the section, we correlate the Massacre Lake beds with earliest Chron C5Cr (16.4-17.3 Ma). In addition, a number of other early Barstovian magnetostratigraphic sections with Proboscidea are reviewed, and quite a few yield fossils that date between 15.8 and 16.2 Ma. Our analysis of faunal data suggests that these early occurrences are simply the first places colonized by the immigrating proboscideans and not marked by a unique ecological or taphonomic history. -
The Fossil Proboscideans of Bulgaria and the Importance of Some Bulgarian Finds – a Brief Review
Historia naturalis bulgarica, The fossil proboscideans of Bulgaria 139 16: 139-150, 2004 The fossil proboscideans of Bulgaria and the importance of some Bulgarian finds – a brief review Georgi N. MARKOV MARKOV G. 2004. The fossil proboscideans of Bulgaria and the importance of some Bulgarian finds – a brief review. – Historia naturalis bulgarica, 16: 139-150. Abstract. The paper summarizes briefly the current data on Bulgarian fossil proboscideans, revised by the author. Finds of special interest and importance for different problems of proboscideanology are discussed, with some paleozoogeographical notes. Key words: Proboscidea, Neogene, Bulgaria, Systematics Introduction The following text is a brief summary of the results obtained during a PhD research (2000-2003; thesis in preparation) on the fossil proboscideans of Bulgaria. Various Bulgarian collections stock several hundred specimens of fossil proboscideans from more than a hundred localities in the country. BAKALOV & NIKOLOV (1962; 1964) summarized most of the finds collected from the beginning of the 20th century to the 1960s, the first of the cited papers dealing with deinotheres, mammutids and gomphotheres sensu lato, the second – with elephantids. Sporadic publications from the 1970s have added more material. During the 1980s and the 1990s there were practically no studies by Bulgarian authors describing new material or revising the proboscidean fossils already published. Bulgarian material has been discussed by TASSY (1983; 1999), TOBIEN (1976; 1978; 1986; 1988), METZ- MULLER (1995; 1996a,b; 2000), and more recently by MARKOV et al. (2002), HUTTUNEN (2002a,b), HUTTUNEN & GÖHLICH (2002), LISTER & van ESSEN (2003), and MARKOV & SPASSOV (2003a,b). During the last two decades, a large amount of unpublished material was gathered, and many of the previously published finds needed a serious revision. -

We have attempted to interpret the biogeographical history of trilophodont gomphotheres in the context of the geological evolution of the continents they inhabited during the Cenozoic. To reconstruct this biogeographic history we used DIVA 1.1. This application resulted in an exact solution requiring three vicariant events, and 15 dispersal events, most of them (i.e., 14) occurring at terminal taxa. The single dispersal event at an internal node affected the common ancestor to Sinomastodon plus the clade Cuvieronius – Stegomastodon. A vicariant event took place which resulted in two isolated groups: (1) Amebelodontinae (Africa – Europe – Asia) and (2) Gomphotheriinae (North America). The Amebelodontinae clade was split by a second vicariant event into Archaeobelodon (Africa and Europe), and the ancestors of the remaining genera of the clade (Asia). In contrast, the Gomphotheriinae clade evolved mainly in North America. -

Remains of Zygolophodon turicensis (Proboscidea, Mammutidae) from the coal mines near Bitola, Republic of Macedonia. – Historia naturalis bulgarica, 20: 157-162. Abstract. We report Zygolophodon turicensis (Schinz, 1824) from the Miocene deposits in a coal mine near Bitola, Republic of Macedonia, and refer a misidentified molar from Nerezi near Skopje published in the 1930s to the same species. Zygolophodon turicensis is a new taxon to the fossil fauna of Macedonia, and the finds discussed in the paper are among the few fossils of pre-Turolian age from the country. Key words: Proboscidea, Mammutidae, Zygolophodon, Miocene, Macedonia Introduction The specimens described below are an accidental find from the coal mines of the thermal power station near Bitola in the southwest of the Republic of Macedonia. Found in sandy deposits, the molars most probably belong to the same individual. Material and methods Material: Left and right m2-m3, coal mine near Bitola, stored at the Bitola Natural History Museum (BiNHM), coll. no. 13536. Methods: Dental nomenclature follows TASSY (1996).

A Grazing Gomphotherium in Middle Miocene Central Asia, 10
www.nature.com/scientificreports OPEN A grazing Gomphotherium in Middle Miocene Central Asia, 10 million years prior to the origin of the Received: 16 November 2017 Accepted: 29 March 2018 Elephantidae Published: xx xx xxxx Yan Wu1,2, Tao Deng1,2,3, Yaowu Hu1,7, Jiao Ma1,7, Xinying Zhou1,2, Limi Mao4, Hanwen Zhang 5,6, Jie Ye1 & Shi-Qi Wang1,2,3 Feeding preference of fossil herbivorous mammals, concerning the coevolution of mammalian and foral ecosystems, has become of key research interest. In this paper, phytoliths in dental calculus from two gomphotheriid proboscideans of the middle Miocene Junggar Basin, Central Asia, have been identifed, suggesting that Gomphotherium connexum was a mixed feeder, while the phytoliths from G. steinheimense indicates grazing preference. This is the earliest-known proboscidean with a predominantly grazing habit. These results are further confrmed by microwear and isotope analyses. Pollen record reveals an open steppic environment with few trees, indicating an early aridity phase in the Asian interior during the Mid-Miocene Climate Optimum, which might urge a diet remodeling of G. steinheimense. Morphological and cladistic analyses show that G. steinheimense comprises the sister taxon of tetralophodont gomphotheres, which were believed to be the general ancestral stock of derived “true elephantids”; whereas G. connexum represents a more conservative lineage in both feeding behavior and tooth morphology, which subsequently became completely extinct. Therefore, grazing by G. steinheimense may have acted as a behavior preadaptive for aridity, and allowing its lineage evolving new morphological features for surviving later in time. This study displays an interesting example of behavioral adaptation prior to morphological modifcation. -

Previous reports of Stegomastodon, Rhynchotherium and Haplomastodon from Central Amer- ica are based on incorrect taxonomic identifications or on fossils not definitely diagnostic of these genera. The oldest proboscidean records from Central America (Guatemala, El Salvador, Honduras, and Costa Rica) are Late Miocene (early Hemphillian, ~ 7 Ma) records of Gomphotherium, and this suggests that gomphotheres dispersed from North America to Central America about nine million years after they dispersed from Asia to North America. -
