PhD title: Taxonomy and phylogeny of the hominins from Fejej (Ethiopia): a comparative 
analysis of cranio-dental remains 
Background 
Since 1992, the Fejej Paleoanthropological Research Project has been conducting field surveys in the 
Fejej area, located in the Omo-Turkana Basin in the far south of Ethiopia. These surveys have led to 
the discovery of several dozen Pliocene hominin remains, mainly isolated teeth and a few mandibular 
fragments. Given their age, but above all their morphology, these remains likely correspond to 
Australopithecus anamensis (4.3–3.8 Ma). Their analysis will help to expand the existing body of 
knowledge on this species, and in particular on its variation. This study will enable a broader 
discussion of the origins of the genus Australopithecus, its possible relationship with Ardipithecus 
ramidus (4.8–4.3 Ma), the links between Au. anamensis and Au. afarensis (3.8–3 Ma), and the 
possibility of intraspecific variation within Au. anamensis across the Omo-Turkana basin. 
Aims of the thesis 
1. I n-depth and comprehensive morphological and morphometric analysis of the craniodental remains 
from the Fejej area. 
2. Analysis of the contribution of Pliocene specimens from the Fejej region to the morphological and 
metric variation in the teeth of Au. anamensis, in comparison with dental variations in Ar. ramidus 
and Au. afarensis. 
3. Intra-basin comparisons of fossils from the Omo-Turkana (specimens from the south-west of the 
basin versus specimens from the north-east). 
4. Cladistic analyses. 
5. Interpretation of all the results, whether intraspecific (including any intra-basin differences) or 
interspecific, from an evolutionary perspective, incorporating available palaeoenvironmental data 
(fauna, isotopic analyses, sedimentology, etc.) available, either through intra-team discussions within 
the Fejej Paleoanthropological Research Project, or via the literature for other sites, particularly those

Opinion | Beware conservatives promoting “intellectual freedom” Victor Ray: This conservative lie about schools like mine is furthering authoritarianism

Important read by @victorerikray.bsky.social about the anti-intellectualism centers popping up at universities across the US. Also critical to point out universities are hypocritically & simultaneously shutting down departments born from ‘movements for broader inclusion in mainstream American life.’

My God, another shooting by ICE, another person dead in Minneapolis.

This is outrageous. None of this is necessary. It is a choice, by Donald Trump, to send thousands of masked agents into a major American city and brutalize people on the streets.

No honest real American can stand for this.

Earth's largest land animals are limited by salt.

Sodium availability constrains the density and distribution of elephants, giraffes and rhinos across Africa, and offers a new explanation for the so-called 'missing megaherbivores'.

Fossils reveal anacondas have been giants for over 12 million years Andrés Alfonso-Rojas has analysed giant anaconda fossils from South America to deduce that these tropical snakes reached their maximum size 12.4 million years ago, and have remained giants ever since.

Fantastic work by #HeadLab PhD student Andrés Alfonso Rojas!

Anacondas have been (resiliently) giant since at least the middle Mioncene.
