A New Astrapothere (Mammalia, Meridiungulata) from La Meseta Formation, Seymour (Marambio) Island, and a Reassessment of Previous Records of Antarctic Astrapotheres

  title={A New Astrapothere (Mammalia, Meridiungulata) from La Meseta Formation, Seymour (Marambio) Island, and a Reassessment of Previous Records of Antarctic Astrapotheres},
  author={Mariano Bond and Alejandro Kramarz and Ross D.E. Macphee and Mar Reguero},
ABSTRACT During the past quarter century, the uplifted nearshore sediments comprising the Eocene La Meseta Formation (LMF) of Seymour (Marambio) Island have produced a diverse assemblage of terrestrial mammals that closely, but not exactly, resembles late Early Eocene faunas from southern Patagonia. This assemblage includes the only astrapothere and litoptern fossils known from outside South America. The occurrence of astrapotheres in LMF was originally indicated by fragmentary dental remains… Expand
Astrapotheres from Cañadón Vaca, middle Eocene of central Patagonia. New insights on diversity, anatomy and early evolution of Astrapotheria
Astrapotheria is one of the most emblematic groups of endemic South American ungulate-like extinct mammals, traditionally compared with modern tapirs and rhinos. Oldest astrapotheres are known fromExpand
Eocene ungulate mammals from West Antarctica: implications from their fossil record and a new species
Abstract Here we describe a new terrestrial mammal from the Eocene of Seymour Island (Isla Marambio) represented by a lower left third molar and assigned to a new species of Sparnotheriodontidae, anExpand
On the status of Isolophodon Roth, 1903 (Mammalia, Astrapotheria) and other little-known Paleogene astrapotheres from central Patagonia
Isolophodon would represent an early diverging lineage of astrapotheriids, in which some dental features evolved convergently with the more derived uruguaytheriines. Expand
Astrapotherium from the Middle Miocene Collón Cura Formation and the Decline of Astrapotheres in Southern South America
Astrapotherium is the better-known member of the placental Order Astrapotheria. This large herbivorous inhabited the Patagonian ecosystems during Early and middle Miocene times. The genus is widelyExpand
Eocene Basilosaurid Whales from the La Meseta Formation, Marambio (Seymour) Island, Antarctica
Abstract. Basal fully aquatic whales, the basilosaurids are worldwide known from Bartonian—Priabonian localities, indicating that this group was widely distributed during the late middle Eocene. InExpand
New Metatherian Mammal from the Early Eocene of Antarctica
Several features suggest the allocation of this specimen among basal polydolopimorphians (Prepidolopidae or, more probably, Glasbiidae), which could offer new insights on the origins and early diversification of Australidelphian marsupials in southern (and northern?) continents. Expand
The oldest mammals from Antarctica, early Eocene of the La Meseta Formation, Seymour Island
New fossil mammals found at the base of Acan- tilados II Allomember of the La Meseta Formation, from the early Eocene (Ypresian) of Seymour Island, represent the oldest evidence of this group inExpand
Considerations about the Evolutionary Stasis of Notiolofos arquinotiensis (Mammalia: Sparnotheriodontidae), Eocene of Seymour Island, Antarctica
Abstract. Notiolofos arquinotiensis is the most abundant terrestrial placental mammal in the Paleogene of the Antarctic continent. Evidence suggests a South American origin of Sparnotheriodontidae,Expand
An ‘ameridelphian’ marsupial from the early Eocene of Australia supports a complex model of Southern Hemisphere marsupial biogeography

An isolated ankle bone of a metatherian from the early Eocene Tingamarra Local Fauna in northeastern Australia is described and compared with a range of marsupials and stem-metatherians strongly suggest that the absence of the CLAJP in QM F30060 is plesiomorphic, and that this specimen represents the first unequivocal non-australidelPHian (‘ameridelphian’) meetatherian known from Australia.

Eocene squalomorph sharks (Chondrichthyes, Elasmobranchii) from Antarctica.
Rare remains of predominantly deep-water sharks of the families Hexanchidae, Squalidae, Dalatiidae, Centrophoridae, and Squatinidae are described from the Eocene La Meseta Formation, Seymour Island,Expand


A new oligocene astrapothere (mammalia, meridiungulata) from patagonia and a new appraisal of astrapothere there phylogeny
A phylogenetic analysis based on dental and mandibular characters indicates that Maddenia lapidaria is, rather, the sister group of the giant Deseadan and later astrapotheriids by sharing with them a well developed upper molar crista and crochet, P4 lingual valley, p2 absent and superficial premolar and molar hypoflexid. Expand
An additional record of a placental mammal (Order Astrapotheria) from the Eocene of West Antarctica
Recently, fossil land mammals have been recorded in the James Ross Island area, east of the Antarctic Peninsula, from the marine middle-late Eocene strata of Seymour Island. These include two endemicExpand
New Discoveries of “Opposum-Like” Marsupials from Antarctica (Seymour Island, Medial Eocene)
Five new species of marsupials are described from the middle Eocene La Meseta Formation of Seymour Island, Antarctic Peninsula. Three are derorhynchid didelphimorphians; one species is a prepidolopidExpand
New marsupial (Mammalia) from the Eocene of Antarctica, and the origins and affinities of the Microbiotheria
We describe and comment on an isolated upper molar belonging to Woodburnodon casei gen. et sp. nov. (Mammalia, Marsupialia, Microbiotheria, Woodburnodontidae fam. nov.), from the Eocene of the LaExpand
A new ‘South American ungulate’ (Mammalia: Litopterna) from the Eocene of the Antarctic Peninsula
Abstract Notolophus arquinotiensis, a new genus and species of the family Sparnotheriodontidae (Mammalia, Litopterna), is represented by several isolated teeth from the shallow-marine sediments ofExpand
New remains of Astraponotus (Mammalia, Astrapotheria) and considerations on Astrapothere cranial evolution
These characters look astonishingly derived for an Eocene astrapothere, suggesting that extreme cranial specializations occurred independently during the evolution of the order, and that Astraponotus represents a distinctive lineage from that of Astrapotherium and other Miocene forms. Expand
