Fossil bird bones from the late Eocene Keasey Formation and the latest Eocene Pittsburg Bluff Formation in northwestern Oregon are the earliest records of the pelecaniform family Pelagornithidae for the Pacific Basin. These fossils also represent the first late Eocene records of the family from the Northern Hemisphere, the second late Eocene record worldwide, and indicate that these animals were among the largest of flying birds. Unfortunately, the fragmentary condition of these fossils and the… 

A basilosaurid archaeocete (Cetacea, Pelagiceti) from the Late Eocene of Oregon, USA

These vertebrae represent the first confirmed specimen of a Late Eocene basilosaurid from the North Pacific, and are reviewed here in the context of LateEocene paleoceanography and cetacean evolution.

First record of fossil birds (Pelecaniformes: Pelecanidae and a probably Odontopterygiformes: Pelagornithidae) from the Upper Miocene of Costa Rica

For the first time, remains of two fossil marine birds are recorded for Costa Rica; these fossils came out from the Upper Miocene Curre Formation. These finds are associated to shallow marine

Diversity of pseudo-toothed birds (Pelagornithidae) from the Eocene of Antarctica

The oldest Antarctic pseudo-toothed bird is reported, represented by an incomplete humerus lacking its proximal end, which comes from the lower Eocene levels of the La Meseta Formation (Seymour Island) and facilitates a review of all known pelagornithids from this continent.

Review of the putative Phorusrhacidae from the Cretaceous and Paleogene of Antarctica: new records of ratites and pelagornithid birds

There is no empirical evidence for the presence of terror birds in Antarctica, and the indeterminate Pelagornithidae specimen represents the largest pseudo−toothed bird known so far.

Latest Pacific Basin Record of a Bony-Toothed Bird (Aves, Pelagornithidae) from the Pliocene Purisima Formation of California, U.S.A.

ABSTRACT Fossils of pelagornithids (bony-toothed birds) have been reported from strata of Paleocene to Pliocene age, and from every continent. The extreme fragility of pelagornithid bones has no

Bony‐toothed birds (Aves: Pelagornithidae) from the Middle Eocene of Belgium

The coracoid distinctly differs from that of extant ‘pelecaniform’ birds, and the plesiomorphic presence of a foramen nervi supracoracoidei as well as the absence of a well‐delimited articulation facet for the furcula supports a position outside the Suloidea, the clade to which the Sulidae belong.

Partial Skeleton of a Bony-Toothed Bird from the Late Oligocene/Early Miocene of Oregon (USA) and the Systematics of Neogene Pelagornithidae

It is detailed that a clade of Neogene species, which the Oregon pelagornithid is not part of, can be supported by a derived morphology of the femur, and classification of all Neogene pelagORNithids in the latter taxon is suggested.

Osteology of a New Giant Bony-Toothed Bird from the Miocene of Chile, with a Revision of the Taxonomy of Neogene Pelagornithidae

An exceptionally well-preserved giant species from the late Miocene of the Bahía Inglesa Formation in northern Chile, in which most major limb bones are complete and uncrushed, that is one of the largest known pelagornithids and the three-dimensionally preserved bones allow recognition of many previously unknown osteological features.

Pseudotoothed Birds (Aves, Odontopterygiformes) from the Early Tertiary of Morocco

This work provides evidence that Dasornis was widespread in the early Tertiary, as it is currently known from the Lower Paleogene deposits of Morocco, England, and Kazakhstan, and Paleoenvironmental studies show that these marine deposits formed in a tropical climate.



A pseudodontorn (Pelecaniformes: Pelagornithidae) from the middle Pliocene of Hawera, Taranaki, New Zealand

These specimens extend the world geological time range for this family of extinct birds into the middle Pliocene, the first record of a pseudodontorn from the North Island, and the third for New Zealand.

Middle Tertiary molluscan zones of the Pacific Northwest

Cassid gastropods are useful in delineating molluscan zones of the late Paleogene and early Neogene and in correlating between isolated basins of marine strata in Oregon, Washington, Alaska, and that

Oligocene marine mollusks from the Pittsburg Bluff Formation in Oregon

The first recorded collection of fossils from the Pittsburg Bluff Formation was identified by W. H. Dall in 1896 and was assigned to the Oligocene. This was the first marine fauna on the Pacific

A historical review of the modest record of Oregon's fossil marine mammals as revealed to date will demonstrate how slow and sporadic has been the rate of progress from the beginning until now; then, a preview of things to come will indicate the striking contrast to be expected in the near future.
