What extinct animal

[Square Wheels]

would you bring back, and why?

 

I think it would be fun to see a pterodactyl, or walk down the street with a baby velociraptor on a leash.

Raptors....I don't like people.  The carnage would be fun to watch.

I can never remember if the duck billed platypus is extinct or not.  My current guess is not. :)Here w

 

Here we go - from Wikipedia:

 

Except for its loss from the state of South Australia, the platypus occupies the same general distribution as it did prior to European settlement of Australia. However, local changes and fragmentation of distribution due to human modification of its habitat are documented. Its current and historical abundance, however, are less well-known and it has probably declined in numbers, although still being considered as common over most of its current range.^[45] The species was extensively hunted for its fur until the early years of the 20th century and, although protected throughout Australia since 1905,^[58] until about 1950 it was still at risk of drowning in the nets of inland fisheries.^[41] The platypus does not appear to be in immediate danger of extinction, because conservation measures have been successful, but it could be impacted by habitat disruption caused by dams, irrigation, pollution, netting, and trapping.^[2] The IUCN lists the platypus on its Red List as Least Concern.^[2]

The carrier pigeon. Evidently they were good eating!
