Perhaps the most remarkable Neotropical dinosaurs are the pachamacs, gigantic ornithopod dinosaurs that look like mirror-images of the true, saurischian sauropods that were once abundant throughout South America. The origin of the pachamacs is obscure, but genetic studies suggest their closest...
Many aspects of the Spec-Australian biota are unique and bizarre, none more so than the 30 species of rhynchoraptors, carnivorous ornithopods that dominate the large predator guilds of this continent, their only major competition being flightless pterosaurs known as carnocursors. They are...
Across the warmer parts of the globe, herds of giant herbivorous ornithopods dominate the landscape. However, when trudging through the forests and swamps of tropical Asia, and to a lesser extent tropical Africa and South America, observers will often come face to face with dinosaurs of a very...
Living hadrosaurs can be divided into two broad groupings. The neohadrosaurs are, despite their name (which refers to their diversity in the New World), the older and more conservative of the two and are found throughout the Americas and the eastern half of Eurasia (The other great hadrosaur...
Although their ancestors seem to have been fairly ordinary-looking generalist ornithopods, Laurasiornithopoda of today consists of three highly derived clades, each adapted to a very different lifestyle. The jackalopes (Struthiodactylidae) have remained most true to their ancestors' lifestyle...
South America is a continent of many oddities, from the enigmatic mergaraptors to the giant pseudosauropods, the pachamacs, but the dinoceratopsians have proven to be some of the Neotropics' most frustrating and fascinating creatures. The ancestors of the dinoceratopsians, primitive...
No group of dinosaurs best expresses the innovation yet familiarity of Spec’s fauna as ungulapedes. Clearly hadrosaurian in nature, the origins of these dinosaurs extend as far back as the Cretaceous. With over an estimated 150 species, these are one of the most successful groups of dinosaurs in...
More like giant geese than non-avian maniraptorans, the strange, unwieldy therizinosaurs are decidedly odd members of the famously oddness-prone maniraptor clade. Like all maniraptors, therizinosaurs (or segnosaurs as they are synonymously called) are bipedal, covered in feathers, and have hands...
Penguins ply the southern seas of this timeline and ours and are known as Paleocene fossils from both worlds. This would suggest that the sphenisciformes had already appeared by the end of the Cretaceous or that presence/absence of the K-T event had little impact on the evolution of penguins...
Spec's birds are puzzling creatures, but few bird groups have proved as troubling as the xenorniths. After a very confusing history of many different classifications (members of this clade have, at times, been classified as euornithians, oviraptorosaurs and enantiornithians), Xenornithes has...
The water-loving, herbivorous ducks and geese are quite an ancient group that reaches back to the Late Cretaceous. After their inception these fowl spread quickly across the surface of both our worlds and can now be found on every continent but Antarctica. For the most part, specworld...

On Home-Earth, the modern Piciformes is made up of six clades: the widespread woodpeckers, piculets, and wrynecks (Picidae), the barbets (Capitonidae), the honeyguides of Africa and southern Asia (Indicatoridae), the toucans of Central and South America (Ramphastidae), and the tropical American...
On Home-Earth, Apodimorphaea includes a number of species, including swifts and hummingbirds. In Spec, however, this clade is somewhat more restricted, relegated almost entirely to the Americas. Until the middle of the Cenozoic, it seems, Spec's p-apodimorphs enjoyed a more global spread of...
Some of the differences between Specworld's biota and that of our timeline are shatteringly apparent. Others, like the twitiaviforms, are of a far more subtle nature. The first Specworld explorers, once the novelty of walking with dinosaurs had worn off, were astounded (or disappointed) by the...
At the end of the Cretaceous, as Spec and Home-Earth began to diverge, birds had already been evolving for at least 80 million years and had diversified widely. In fact, the diversity of bird types (though not actual species count) was far higher in the late Mesozoic than it is today in our...

The most common of the deinonychosaurs (with mattiraptors a close second), the draks are the unquestioned lords of virtually all medium-sized predator niches in Africa, Eurasia, and North America. Little different from their Cretaceous forebears, draks are often heavily-plumed and many bear the...
