Speculative Evolution Project

[Stegotyranno420]

Hello everyone! I'm working on a speculative evolution project about an alternate timeline where some non-avian dinosaurs survive the K-PG event, and they thrive during the Cenozoic era, eventually wiping out mammals, squamates and birds due to competition. Theres two main parts in the project (the world during 30 mya, and the world 25 million years in the future.)
I need help because I need to know the last non-avian dinosaurs(by region/country/continent)
Other animals are also welcome, such as pterosaurs, mosasaurs, etc

March 27, 2020 edit: I am wondering if will be able to make this a group project. If you have ideas or drawings, PM me. But there are rules.

1. Sapient groups, genetic engineering, squamates,mammals, aliens, kaijus, and birds are not allowed, due to the nature of the plot
2. If you are sending a organism, include weight, height, length,diet, time era, scientific name, common name, and country/region(examples: East India, West America, North Germany)

P.M. Me if you want to join

Your best bet is to look at all fauna from the last age of the Mesozioc Era, and that would be the Maastrichtian Age. There's quite a bit to name, but some of the classics were there:
Tyrannosaurus
Triceratops
Alamosaurus
Ankylosaurus
Pachycephalasaurus
Edmontosaurus
Quetzalcoatlus'
Mosasaurus
Velociraptor
Carnotaurus
Gallimimus
Struthiomimus
Ornithomimus


...just to name a few.

Thank you, but how about Maastrichtian age dinosaurs/animals in India, Africa, Europe and the rest of South America

Terrestrial fauna in the end-Cretaceous were fairly endemic, meaning that groups that were common in North America & Asia were largely absent everywhere else, and vice-versa. The only real exceptions to this rule seem to have been titanosaurs, which were the only sauropods left at this point but had near-cosmopolitan distribution; hadrosaurs, which were present in South America and Europe; ankylosaurs, which are known from Antarctica and may be descended from an endemic polar fauna rather than any Asia-American clade; alvarezsaurs, small bird-like animals with short, robust limbs that may have been specialised termite-hunters; and unenlagiines, a type of fish-eating dromaeosaur (or basal avialan) which were most common in South America and may have spread to Africa & Australia.

The main dinosaurian predators were of course the abelisaurs, while their enigmatic relatives, the noasaurs, represent the primary smaller predators, with some evolving to eat fish and others possibly being herbivorous ornithomimosaur-mimics. Titanosaurs were the main herbivores, growing from less than 8 metres in the European archipelagos to over 30 on the South American plains. Many may have evolved to fill ecological niches that were occupied by animals such as hadrosaurs, ceratopsians and ankylosaurs on the northern continents, and their evolution and diversity is poorly understood. Basal ornithopods known as elasmarians were the primary small-medium sized herbivores in the Southern Hemisphere, growing from ~1.5 to more than 7 metres long, while the similar rhabdodonts (which may also be elasmarians) filled a similar niche in Europe. True hadrosaurs, while rare, were present, moreso in Europe than the Southern Hemisphere.

Quoting Holtz ( https://www.geol.umd.edu/~tholtz/G104/lectures/104extinct.html ):

On land, victims include:

Bennettitalians: a group of Mesozoic plants related to the ancestors of the flowering plants
Various types of mammals
Various types of land-dwelling crocs (including the herbivorous crocs)
Pterosaurs (only larger pterodactyloids known from Late K)
Most kinds of dinosaurs present at the time:
Saltasaurid and aeolosaurid titanosaurs (last surviving sauropods)
Abelisaurids and noasaurids (last of the ceratosaurs)
Tyrannosaurids and a few basal tyrannosauroids
Ornithomimids (and deinocheirids?)
Caenagnathoid oviraptorosaurs
Therizinosaurids
Troodontids
Dromaeosaurids
Alvarezsaurids
Enantiornithines
Hesperornithine, and a few other basal euornithine bird groups
Nodosaurids
Ankylosaurids
Thescelosaurids
Rhabdodontids
Hadrosaurids (both lambeosaurines and hadrosaurines)
Pachycephalosaurs
Leptoceratopsids
Ceratopsids (although only chasmosaurines are currently known from the very end of the Cretaceous)

Thanks, everyone. Does  anyone  want to contribute to the project
