The gold rush has begun. Restored animal populations will gain massive public support and scientific investment for literally decades. A facility like this will mine every sample for genetic information.
That leads to reconstruction even if it happens a bit at a time. sooner or later it becomes possible to transition an elephant embryo toward the correct DNA to allow the emergence of these extinct animals. That will include the mammoth and the mastodon.
At the same time we can expect to see the whole Pleistocene menage developed concurrently as we become more adept.
