A skeleton from the Cretaceous found in Japan reveals an early bird with a tail nub resembling the avians of today. Rheidae - Rheas 3.1. The oldest known fossil unambiguously identified as a bird is still the dinosaur-like Archaeopteryx, from the Solnhofen Limestoneof the Upper Jurassicof Germany. The fossil, from Belgium, has been dated back to almost 67 million years ago - meaning that the birds lived alongside dinosaurs for around a million years before the latter died out. Traditionally placed within the Gruiformes, they are usually considered a distinct order nowadays and appear closer to the Anseriformes. These fossil taxa cannot be assigned to any major group with reasonable certainty. †Emuarius (Late Oligocene - Late Miocene) - formerly Dromaius 2.2.

Archaeopteryx , sometimes referred to by its German name, Urvogel ("original bird" or "first bird"), is a genus of bird-like dinosaurs that is transitional between non-avian feathered dinosaurs and modern birds. Clockwise from upper left: Southern Screamer (Anhimidae), Magpie Goose (Anseranatidae), West Indian Whistling Duck (Anatidae), Coscoroba Swan (Anatidae).

“It is basically four small blocks of rock with a handful of broken limb bones visible, poking out of the rock,” he said. Casuariidae - Emus and cassowaries 2.1. Ostrich and related ratites. This page contains a listing of prehistoric bird taxa only known from completely This category contains very early fossils that some consider the earliest evidence of birds and others which are generally agreed to be The most primitive birds, usually still possessing a long bony tail with generally unfused vertebrae. Tiny creature, half the size of a mallard, found in rocks dating back to dinosaur ageExperts have discovered a fossil of the world’s oldest known modern bird – a diminutive creature about half the size of a mallard duck.Dubbed the Wonderchicken, the remains were found in rocks dating to about 66.8m to 66.7m years ago, revealing that the bird was active shortly before the asteroid strike that wiped out the dinosaurs 66m years ago.“This is the oldest evidence of modern birds that we have so far,” said Dr Daniel Field, of the Modern birds evolved from meat-eating theropod dinosaurs, with creatures such as the 150 million-year-old It is not clear exactly when modern birds emerged, but estimates range from about 110m years to 85-70m years ago.“As best as we can tell, this fossil sits very close to the common ancestor of two major groups of living birds – the group that eventually gave rise to chickens and their relatives, and the group that eventually gave rise to ducks and their relatives,” Field said.The team says the discovery pushes back the date of the earliest known modern bird: the record was previously held by At first, said Field, the specimen appeared unprepossessing. Between the late 19th century and the early 21st century, Archaeopteryx was generally accepted by palaeontologistsand popular reference books as the oldest known bird (member … †Hinasuri 4. †Palaeoti… 1. However, on digitally “removing” the low-density rock around the fossil using computer software, the team found something special.“As soon as I did that, this incredible skull – one of the most incredible fossil bird skulls in the world – stared straight out at us, and we could not believe our eyes,” said Field, noting that the lack of teeth and other features of the skull quickly suggested it was from an early modern bird.“We thought that that was apropos because the fossil is so close in time to the asteroid impact,” said Field, adding the Greek myth describes Asteria being transformed into a quail and throwing herself into the ocean to avoid Zeus, features that nod both to the animal and the habitat in which it may have lived.The team say the fossils not only suggest modern bird evolution was in its early stages when the asteroid struck, but its discovery in Europe opens up debate about whether modern birds emerged in the southern hemisphere, as has previously been proposed.Prof Julia Clarke, an expert in avian palaeontology and “Finding this new fossil in Europe is key to understanding a global pattern of extinction and survivorship in the Latest Cretaceous,” she said. †Heterorhea(Pliocene) 3.2. †Aepyornithidae - Elephant Birds 4.1. However, a growing number of unusually well-preserved fossil birds are contributing much to our understanding of bird evolution.
