Of course, there are individual variations as to whether someone is tall or short, but even this compilation of 3D reconstructions of the head specimens on the same scale shows very impressively how size increases. The interocular distance may serve as a reliably comparable measure, and it can be seen, that it definitely increases overall, albeit the individuals with crown-rump lengths of 22–25 mm in particular also show that there can be specific variations. There are also individual variations with regard to the vertical dimension of the face, if you take the distance between the height of the eyes and the chin region. Interestingly, the musculature is already quite well developed in the first stage of development here, which is at 19 mm CRL. Apart from that, however, all embryos and fetuses show that there is a clear increase in the maturation of the cartilaginous and bony structures of the face.
