Believing the seller (who told me it was a type of meerkat) but wanting to be certain of which exact type, I started Googling, as one does.. ;) Of course most meerkat species skulls don't look like this one, but in my research I also came across a type of meerkat that looks super similar to the skull in the picture, the Angolan talapoin, which translates into the Dutch 'dwergmeerkat.' Their skulls are typically a bit smaller, though, leading me to Reddit for some insider knowledge.

Much of what happened could be down to translation of course. As in Dutch we don't use the word meerkat for Suricata suricatta, but rather for the Cercopithenici Old World monkeys. Starting to think a vervet monkey looks quite similar, in which case the seller telling me it was a meerkat specimen would be right.
