Among the many issues with the fossil record is the case of gender identification. In modern organisms, it is usually pretty easy to tell which members of a particular species are the males and which are the females. This can either be through consistently perving on them to figure it out during copulation, or some aspect of their morphology, such as antlers, or you know, a penis or vagina. When it comes to fossil though, we often don’t find these typical gender-distinctive aspects of morphology preserved, as they are usually lost in one form or another to the ravages of time and the process of fossilisation.
