A Tumblr dedicated to anything related to human osteology.

Two weeks ago I was looking some topics for my project. I couldn’t find anything useful but I did stumble upon a good online course of osteoarchaeology: Osteoarchaeology: The Truth in Our Bones | Coursera 

The course is for anyone and requires no previous knowledge of the area. However, those people that are just beginning their formation or want to remember somethings of the discipline will be the most interested in taking it.The course is offered by the Universiteit Leiden and is divided in 5 weeks:Presentation, basics, estimation of sex, age and height.PaleopathologyDietPhysical activityMobility and MigrationI’m currently at week 2 and so far so good.“

Did you know it is normally a pair of tibiae the two crossed bones in the pirate flag?

There's also a draining sinus of +1cm long at the same site with evident sign of periostosis. Source: https://osteoruiz.quora.com/Infection-in-fractured-tibia?share=6f9e4576&srid=35ddG

My old professor shared a photo like the one above, and I wanted you to see it too.

Can you tell me what is wrong with this? There are a few things not right with the skeleton.

Hint: Anatomical position.

UPDATE: From what I can observe, here is everything I noticed wrong with the bones shown by the image above.

1. The scapulae need to be placed in anatomical position. The Articular Surface of the Glenoid Cavity (where the humeral head goes) must point laterally.

2. The clavicle (collarbone) on the right side of the image needs to be placed in anatomical position. The larger/rounded end is the Sternal Facet which faces medially, and the Acrominal Facet (flat end) faces laterally.

3. The vertebral column needs to also be placed in anatomical position. The spinous process of each vertebrae must face posteriorly.

Note: I would not place the mandible under the weight of the cranium. Bones are evidence, we must try our best not to damage them while we observe. It is best to sit the cranium on a beanbag sort of cushion, or small pillow during observation. I would have the mandible near its appropriate anatomical position location for referencing, just not right underneath the cranium if it does not sit well.

Multiple ribs are wrong sided, too.

Had a fire on a beach tonight and did a little beach combing. Got some nice little desk ornaments! Not sure what most of them are… Other than one looks like an oyster shell and probably a seagull scapula (L) . I’m not looking for an ID but I do think they’re super cool!
