Happy October! This month is national archaeology month; so here’s a cute and spooky fact. Skeletons that have porous lesions lived a life with an iron deficiency. As seen above and indicated by arrows. Image courtesy of google, spookiness courtesy of October 🎃

Why must the internet hurt me like this? 😫 😫 😫

This is still my favorite post on this whole site
i’ve been crying laughing over this for the past 5 minutes
I really want to study anthropology in college and hopefully one day be a forensic anthropologist. I’ve heard that there’s a lot of math involved and I’m completely awful at math. (Seriously. However bad you think I am, I’m worse.) how much of a problem will that be? Any advice?
The only math I used regularly was statistics. I do wish I had taken a physics course at some point because it would’ve been handy to understand biomechanics and maybe get into ballistics, but none of that is necessary. Some schools will want you to have a higher quantitative GRE score, which is why I didn’t get into one PhD program - the professor I wanted to work with does really heavy statistical analyses. But by and large it’s not a dealbreaker, so still go for it!!
Body size, scaling body size, and how shape changes.
Helps in a forensic context for the biological profile.
Population, and environmental stressors like mobility, and disease affect body size/shape. Can also be used to understand the sexual dimorphism of extinct hominins. Ecogeographical rules related to thermoregulation: Bergmann’s Rule (1847) If you have a species that is variable, and spread out over a geographical area you will see a larger variance of those species. Relating to body mass; bigger in colder climates, smaller in warmer climates. Allen’s Rule (1877) concerned with appendage’s. Shorter in colder climates, and longer in warmer climates. Together they are Bergmann’s and Allen’s rules.
A great modern example is the observed in the following populations:
Inuit, Shorter limbs, and rounder stocky body:

Maasai, Longer limbs, slender taller body:

This is showing basic phenotypical adaptations to different climates, and how the environment can biologically change populations.
Note: Diet, nutrition, humidity, and variation (and many other variables) play a role in phenotype.
The metopic suture (also known as the frontal, interfrontal, or median frontal suture) is a type of calvarial suture. The suture is often associated with frontal sinus agenesis/hypoplasia.
In some individuals, the suture can persist (totally or partly) into adulthood. The persistent frontal suture is of no clinical significance, but can be mistaken for cranial fractures and is useful in the forensic identification of skeletal remains.

Bone Of The Week: Ulna (2)
Image Source: Anatomography. Ulna.Wikimedia Commons.
The Ulna is the longest and thinnest of the two long bones located in the forearm. At the elbow, the ulna articulates with the trochlea of the humerus and with the radial head. Distally (at the wrist) the ulnar notch of the radius articulates with the ulna. These articulations allow the ulna to provide freer rotation of the hand and radius.
Some notable landmarks of the ulna include:
(From Elbow (Proximal) to Wrist (Distal).
Olecranon Process: Located posteriorly and inserts into the olecranon fossa of the humerus. It is the most proximal and larger end of the bone. The triceps brachii muscle (the primary extensor of the forearm) inserts on the tuberosity of this process. (Image A #1, Image B #6)
Coronoid Process: The process that fits into the coronoid fossa of the humerus. (Image A #3)
Trochlear notch: Also known as semilunar, articulates with the trochlear surface of the distal humerus (at the elbow). (Image A #2)
Radial Notch: Where the head of the radius sits located on the lateral margin of the coronoid process. (Image A #4)
Interosseus Crest: (Or border) is the sharpest border of the ulna which is located opposite to the radius. (Image B, border left of #7)
Extensor Carpi Ulanris Groove: Here rests the tendon of the extensor carpi ulnaris muscle. (Image B, groove to the right of #11)
Styloid Process: On the posterior (back part) of the ulnar head is the most distal projection of the bone. It is sharp, and here the ulnar collateral ligament of the wrist attaches. (Image A #7, Image B #11)

NOTE: Not all landmarks are mentioned. Remember to follow anatomical positioning and referencing.
This is an example of a skull with Osteosarcoma. Osteosarcoma, or bone cancer, starts in growing bone cells, called osteoblasts, and results in abnormal bone growths. About 8% of osteosarcomas happen on the cranium, more often it occurs in the arm and leg bones. Because Osteosarcoma forms while bones are growing, it is most common in children and young adults.
reblog this if you're an anthropologist, an archaeologist, or an anthropology or archaeology student
biological, cultural, linguistic, archaeology… I want to follow you!
My goal for the Fall 2019 semester is to intern at the Forensic Anthropology Unit (FAU) here at the New York City’s Office of Chief Medical Examiners (OCME).
As you can see there are a few requirements. Currently I am taking the human osteology course, and next semester (Spring 2019) I will enroll in the interpretion of human skeletal remains course. I need a minimum grade of A- to be considered for the internship, however, I am aiming for an A in both courses!

Non Metric Traits
Non-metric traits, also known as discrete traits, discontinuous morphological traits, or epigenetic variants, are a part of normal human variation and are not pathological in nature. As the name suggests, it is thought that they have some sort of genetic basis. They are usually recorded as either “present” or “absent,” or they can be scored on a continuous scale. Their very nature means that they can’t often be quantified, though they can be used in conjunction with other things for identification of an individual or for population studies.
Often subdivided into cranial, dental, and postcranial traits, they can be extra bones, articular differences, variations in the number of foramina, extra ossification of a particular feature, or ossification failure.
Non-metric traits include Wormian bones (top), sternal foramina (2nd row left), metopic sutures which persist into adulthood (2nd row right), calcaneal notches (bottom), third trochanters of the femur, and vertebral number shifts, among other things. Dental metric traits in particular, such as shoveled incisors or differing cusp numbers, can be used to guess population affinity.
