A new fossil species of small crested caracara (Aves: Falconidae: Caracara) from the Pacific lowlands of western South America

  title={A new fossil species of small crested caracara (Aves: Falconidae: Caracara) from the Pacific lowlands of western South America},
  author={William Su{\'a}rez and Storrs L. Olson},
Abstract A new species of small crested caracara, Caracara seymouri, from Quaternary asphalt deposits of the Talara Tar Seeps, northwestern Peru, is described from most major elements of the skeleton. Specimens reported in the literature from late Pleistocene deposits at La Carolina, Ecuador, are referred to the same species. These fossils had previously been identified as Polyborus (now Caracara) plancus, but they possess a combination of characters not present in the living species of…

Osteological comparisons of both living and extinct species indicate that the extinct genus Amplibuteo Campbell is synonymous with Buteogallus, and the new taxon was approximately the same size as females of the extinct continental B. woodwardi.

New species of troupial (Icterus) and cowbird (Molothrus) from ice-age Peru

2 new extinct species of icterids from the late Pleistocene Talara Tar Seeps of northwestern Peru are described, including Icterus turmalis and Molothrus resinosus, both known thus far only from Talara.

Ecological and evolutionary legacy of megafauna extinctions

It is argued that the ongoing extinction of the extant megafauna in the Anthropocene will catalyse another wave of co‐extinction events due to the enormous diversity of key ecological interactions and functional roles provided by the megAFauna.



Further characterization of Caracara creightoni Brodkorb based on fossils from the Quaternary of Cuba (Aves : Falconidae)

•Caracara creightoni, previously known from three fragmentary fossils from New Providence Island, Bahamas, is here documented from two Quaternary sites in Cuba. It appears to have been a smaller

Body Mass Estimations and Paleobiological Inferences on a New Species of Large Caracara (Aves, Falconidae) from the Late Pleistocene of Uruguay

F fossil remains of a new species attributed to the genus Caracara from the late Pleistocene of Uruguay are reported, which would have had an estimated body mass that greatly exceeds the maximum body mass reported for living falconids.


Studying plumage characters and measurements of over 392 museum specimens and found no evidence of clinal change between the northern and southern continental populations, it is concluded that three biological species can be identified in the crested caracaras: the insular Guadalupe Caracara (Curacara lutosus); and two continental species, Northern and Southern caracara, neither of which shows subspecific variation.

Exceptionally well preserved late Quaternary plant and vertebrate fossils from a blue hole on Abaco, The Bahamas

The exquisitely preserved fossils from Sawmill Sink suggest a grassy pineland as the dominant plant community on Abaco in the Late Pleistocene, with a heavier component of coppice (tropical dry evergreen forest) in the late Holocene.
