That's about what I was thinking. Maybe female, but too small to be sure. I only have 3 torts for reference, so was hoping someone with a more practiced eye could make a more informed guess.Sorry you haven't got a reply yet, but in my experience, 5" is still a bit too small to be sure on sex with a G platynota. If I were to guess, your tortoise is looking female. But I wouldn't count on that yet at this size. Overall rounder shape, anal scutes, and tail. But that can still change as those things can all change as male characteristics develop around 6"+
Looking male at this point to me. We need to be able to clearly see the tail in future pics. That is the best indicator.
Looking straight at the plastron is best. In all but one photo, the tail is cut off. In the one pic that isn't cut off, the tail is hidden in shadows.L
Like from the back or side?
That tortoise is looking very male to me at this point. I think it is large enough to tell and by the overall shape, it definately looks male. The overall shape is much more oval now. The shape difference normally starts to show by about 500g. The tail is hard to see well, but looks tucked to the side and too long for female. You have a good shot of the tail in your first photos back in Jan, and the tail has changed considerably. 98% sure its male now.
Do you have some good calipers to get exact measurements? If so, I find if you divide the straight carapace length by the straight width, you will never see a male over 550g with that ratio under 1.55. Males tend to all average about 1.62 and females average 1.43 I have one very large female that is 1.55 but that is the only female I have seen that is over 1.50
