KSD-VP-1/29 (Juvenile Australopithecus afarensis mandible) increased the sample size of juvenile hominin mandibles from ca. 3.6 Ma (only one specimen previously ID'd), and contributed to assessments of mandibular morphology of juvenile hominins during this time! #FossilFriday

This immature hominin fossil (TD6) from the European Lower Pleistocene is the earliest evidence of a modern
human dental development pattern; perhaps these hominins had a prolonged childhood within the range of modern humans?! #FossilFriday https://t.co/4XDcbXSbC8

The left tibia of this juvenile Homo naledi (DH7) is quite possibly the best preservation of epiphyses with such a high degree of surface detail in the hominin fossil record! #FossilFriday https://t.co/hrBEPAZM3H

This DNH 134 juvenile crania, sharing affinities with H. erectus, was discovered between 2015 and 2018 at the Drimolen Main Quarry in South Africa and was likely deposited ~2.04 million years ago, predating all known specimen of that species! #FossilFriday

#FossilFriday lives on! Fragments of this juveline hominin's temporal bone (KB 6067) were found at the Kromdraai B site in South Africa. The morphology of this bony labyrinth has affinities with Australopithecus africanus, P. robustus AND early Homo.

We love teeth!! The dental remains of juvenile individual (Stw 151) constitutes the most complete set of nearly hominid child teeth since the Taung child! Developmental analysis indicates the specimin's age was between 5.2 and 5.3 years old. #FossilFriday

Is Australopithicus sediba the elusive link to the Homo clade?! Maybe not. This MH-1 skull of an A. sediba juvenile is actually very intermediate between Taung and adult A. africanus crania, indicating a much closer relation to A. africanus #FossilFriday https://t.co/BVZhwMHdyO

Does everyone know that our favorite juvenile hominin the Taung child (Australopithecus africanus) was probably picked up by a large bird of prey!? The skull shows similar damage to other skulls of eagle prey found at the site! #FossilFriday

Happy Valentine's day to all my fossil lovers!! This week I have the El Sidrón J1 Neandertal skeleton for you which exemplifies all the neat ways you can use ontogeny to study growth patterns and rates of maturation in juvenile hominins! #FossilFriday

I'm back again! With more bones! The maxilla of this Xujiayao 1 fossil, an archaic Homo juvenile, was exhibiting characteristic prolonged dental development comparable to a similarly-aged modern human child! #FossilFriday https://t.co/J0w6p5CK3y

WOW a rare fossilized foot of a juvenile Australopithecus afarensis (DIK-1-1f)!? This rare find indicated the possibility of foot-grasping/ tree-climbing capabilites in this early hominin species previously assumed be an exclusive biped! #FossilFriday

To my dedicated 25 followers who have been with me through so much... I’m going to have to start tweeting about bones every week for my anthropology class. So if you want to unfollow me that makes sense.
Much love,
