While the woolly mammoth is on track to be revived within three years, Lamm said that Colossal's work on the Tasmanian tiger is two years ahead of schedule.
Lamm said Colossal would not be looking to emulate Jurassic Park by bringing back dinosaurs, which he claims is not possible as there are no DNA samples.
A firm that says it can bring back the woolly mammoth 4,000 years after it vanished from the earth has just completed a $200 million (£160 million) funding round.
Lamm says there are ecological benefits to this, adding that the technology may help save endangered species, and benefit human and animal healthcare through new vaccines and artificial wombs.
