Estimating the wingspan

I had enough bones to estimate the size of the wing, so I gave it a try:

In fact, I forgot to add a bone, so that is 40cm smaller than it should be!

The forearm

The forearm consists of two bones. I started as usual, with a drawing sketch, followed by a three-dimensional sketch. I used layers. Here I finished one pair:

Here are some pictures of the pterosaur with arms:

The humeri, tibiae and femora

I had very little time this week, but I was able to slowly carve and model the first bones of the arm and the legs. This is one of the humeri:

These are both humeri, tibiae and femora.

And the pterosaur, with both humeri, and some plans for the forearm (radio and ulna).

These are the plans for the radio and ulna which I will make this week:

Traveling with a pterosaur

I heard there was a plane crash caused by a crocodile which got loose in the plane during landing. The passengers panicked and ran to the back of the aircraft, destabilizing the plane. One survivor told the story, and later the dead crocodile was found.

Hopefully the flight attendants won’t consider my dinosaur a threat. It will travel in this cardboard box:

It is quite fragile, and it would be terrible if a big suitcase fell over its box. Hopefully I will be allowed to take it with me, since it is very, very light (despite being slightly oversize in length).

This is the pterosaur, packed to go.

I will be back as soon as I have time to do something.

Arms and legs

I am going to travel next week, and will be out for three weeks. I hope to have some time to work on some bones. I did some research and came up with these plans for the humerus (the arm):

And the femur (the leg).

I then made some 3D sketches (layers for the legs, and cross-fitted the top and side views for the humerus). I will work on them during my trip.

The tail

I made each tail vertebra and then passed a fishing line through them. I made the tips out of the same material I made the teeth. I then connected them all with silicone rubber, and this is the result.

Cartilage

I used silicone rubber to make some cartilage ribs and connect to the sternum.

The rib cage

Finally I was able to make the ribs look good when connected to the spine and sternum. The last ones I will try to connect with cartilage made from silicone rubber.

It’s getting harder to work with it without breaking something. I found a way to hang it 🙂

It’s quite a flexible bird 🙂

A new notarium

I remade some vertebrae, unassembled the scapulae and coracoid bones, and replaced the notarium with a new one. The old one was not robust enough. I also connected the vertebrae in the pelvis.

A new coracoid (still wrong)

I tried to fit the ribs. They would cross the coracoid. I tried moving it up, down, away. I tested different positions. Finally I decided to make a new one. I made it straight. It is not good yet, I know, but at least it will let me connect the ribs. After I finish this part I will think about how to replace it with a third coracoid.
