I did some more digging and found that Musofa had been identified as rhino number 56 back in 2013. Then in 2020 there was another news report about him. But the information in that article was a bit confusing, because it said he was “around 7 years old” in 2020.
If that were true, it would mean he was 0–1 years old in 2013, which doesn’t make sense, because at that age he wouldn’t have had any clear identifying features yet.
So I tried breaking it down into two possibilities:
1) If he was 7 years old in 2020 → then in 2025 he would be 12.
2) If he was 7 years old in 2013 → then in 2025 he would be 19.
But no matter which way you calculate it, once he died it turned out he was actually 45 years old — which is off by 20–30 years from the previous estimates.
Honestly, I think the method used to estimate the age of wild Javan rhinos really needs to be completely overhauled.
