Before I share this week’s Friday mystery object, I’d like to just take a moment to mark the 100th birthday of Sir David Attenborough.

I think it’s fair to say that he is a national hero in the UK and the source of inspiration for generations of naturalists, thanks to his documentaries. I’ve been fortunate enough to meet the legend himself a couple of times, and he was even generous enough to lend his Elephant Bird egg to an exhibition I was involved in at the Horniman Museum over 10 years ago.

So here’s wishing a very happy century celebration to Sir David!

With that said, here is a nice skull for you to have a go at identifying – I’d love to hear your thoughts on what it might be:
