Macraucheniidae is a family in the extinct South American ungulate order Litopterna, that resembled various camelids. The reduced nasal bones of their skulls was originally suggested to have housed a small proboscis, similar to that of the saiga antelope. However, one study suggested that they were openings for large moose-like nostrils. Conversely, prehistoric pictographs by indigenous people seems to depict animals interpreted as macraucheniids with trunks. Their hooves were similar to those of rhinoceroses today, with a simple ankle joint and three digits on each foot. Thus, they may have been capable of rapid directional change when running away from predators, such as large phorusrhacid terror birds, sparassodont metatherians, giant short-faced bears (Arctotherium) and saber-toothed c

  • Els macrauquènids (Macraucheniidae) són una família de litopterns de Sud-amèrica, descrita per Theodore Gill el 1872 i que inclou animals com ara Macrauchenia o Cramauchenia. (ca)
  • Los macrauquénidos (Macraucheniidae) son una familia extinta de mamíferos placentarios del orden Litopterna perteneciente al clado Meridiungulata. Es el género más reciente de litopterno (vivió en el Pleistoceno). Macrauchenia , fue el único grupo que sobrevivió al gran intercambio americano. Desapareció en el Cuaternario después que el hombre poblara Sudamérica. (es)
  • Macraucheniidae zijn een familie van uitgestorven zoogdieren die leefden van het Tertiair tot het Pleistoceen. (nl)
  • Macraucheniidae é uma família da ordem Litopterna que engloba ungulados endêmicos da América do Sul semelhantes a lhamas, provavelmente dotados de uma pequena tromba. Inclui gêneros como Macrauchenia e Theosodon. É provável que seus membros tenham vivido em grupos, de modo a facilitar a reprodução e evitar predadores, que incluim aves forusracídeas, nas espéciesm mais antigas, e felinos com dentes-de-sabre, no caso da Macrauchenia. Não eram animais bons de corrida, como prova sua morfologia, mas acredita-se que tinham boa noção de mudança de direção. Tinham três dedos em cada pata, de forma semelhante ao dos rinocerontes. (pt)
  • Die Macraucheniidae sind eine ausgestorbene Familie der Säugetierordnung Litopterna, die während des Känozoikums in Südamerika gelebt hat und deren letzte Vertreter erst am Ende des Pleistozäns ausgestorben sind. (de)

  • I Macraucheniidi (Macraucheniidae) sono una famiglia dell'ordine dei Litopterni che comprendeva varie specie estinte di ungulati sudamericani. L'osso nasale posto in posizione piuttosto arretrata nel cranio suggerisce che avrebbero potuto avere una piccola proboscide, o almeno un suo abbozzo. Gli zoccoli, costituiti da una semplice articolazione alla caviglia e da tre dita per ogni piede, sono molto simili a quelli dei rinoceronti. Grazie ad essi, erano in grado di effettuare rapidi cambiamenti di direzione mentre sfuggivano ai predatori, come i grossi uccelli del terrore forusracidi e le tigri dai denti a sciabola del genere Smilodon. I Macraucheniidi probabilmente vivevano in branchi numerosi proprio per difendersi meglio da questi predatori, ma anche per trovare meglio un partner con cu (it)
  • Macraucheniidae – rodzina wymarłych ssaków należących do kopytnych. Zamieszkiwały Amerykę Południową. Budowa ich kości nosowych sugeruje, że posiadały one trąbę. Ich kopyta przypominały te spotykane u dzisiejszych nosorożców. Zwierzęta te posiadały prosty staw pomiędzy stopą i golenią, a także po 3 palce na kończynę. W związku z tym prawdopodobnie były zdolne do szybkich zmian kierunku w czasie biegu, np. ucieczki przed drapieżnikiem takim, jak olbrzymie ptaki Phorusrhacidae czy też szablozębne koty (Smilodon).
