Hello. This is the timeline of tree-kangaroos in Brazil, at least from what I've gathered online.
- May 1972: In a shipment of thirty-five animals, the first tree-kangaroo in Brazil arrives at the São Paulo zoo. Its species was not stated, but I believe it was
Dendrolagus ursinus.

- Between May 1972 and October 1975: another specimen of tree-kangaroo arrived in the country, also sent to São Paulo.
- October 6, 1975: both animals are sent to RioZoo.
- August 1, 1977: for the first time, the couple's first joey, a female, put her paws out of her mom's pouch.
- July 6, 1978: It was announced RioZoo's female had another joey. The new baby was expected to completely leave the marsupium in August.
