Pandorasaurus' Projects

Alternative KT Extinctions is a project of mine about "what if different species survived and went extinct in KT"?

It is an open project so anyone on the SE forums can participate.

Here are the extinct animals of KT:

All anapsids (it includes Testudines).
Squamates.
Sphenodonts.
Choristoderans.
Crocodylmorpha.
Neognath birds (Modern birds).
Non-avian theropods.
Sauropods.
Ornthipods.
Ankylosaurs.
Monotremes.
Eutherian (Placental) Mammals.
Gymnophions (Caecilians (Amphibians)).

Here are the extant animals of KT, along with which continent they live in:

Azhdarchids (NORTH AMERICA, ASIA, EUROPE, AFRICA),
Ceratopsians (NORTH AMERICA, ASIA),
Pachycephalosaurs (They pwn, wonder why nobody knows of them) (NORTH AMERICA),
Ornithocheirods (Used to live nearly everywhere, but by KT restricted to EUROPE),
Pterodantids (NORTH AMERICA),
Opossums (SOUTH AMERICA),
Late Cretaceous Antarctic Marsupials (ANTARCTICA),
Stagodontid Marsupials (no wikipedia articles, watch this and pause at 0:40) (example: didelphodon) (NORTH AMERICA),
Asiadelphere Metatheres (ASIA),
Deltatheroid Metatheres (NORTH AMERICA, ASIA),
Enantiornithes (NORTH AMERICA, SOUTH AMERICA, EUROPE, ASIA),
Hesperornithes (NORTH AMERICA, EUROPE, ASIA),
Paleognaths (SOUTH AMERICA, AUSTRALIA),
Cimolodont Multituberculates (NORTH AMERICA, ASIA, EUROPE),
Gonwandatheres (Semi-aquatic burrowing beaver-like allotheres) (SOUTH AMERICA, AUSTRALIA),
Salamanders (NEAR-WORLDWIDE),
and Frogs (NEAR-WORLDWIDE).

**NOTE** I'm not counting paleognaths and gondwanatheres in Antarctica because they will die off in Antarctica with no survivors by present day. With the marsupials they will enter Australia like present day after KT happens.
 

Here are the sea creatures:

All the extinctions and survivors are the same as HE, except that:
sharks and nautolids are extinct
and ammonoids and belemnoids are extant, and mosasaurs or plesiosaurs are extant.


If mosasaurs or plesiosaurs survive is currently under debate in the forum thread. (it is an open project).

Here is the species page.

Here are the concepts by other SE forums users and myself.
