All the bones are finished. Time to add a protective resin layer and to make some small fixes. Here are some of them drying after receiving a layer of epoxy.
All the bones already have a resin layer except for the cervicals, anterior part of the skull and the scapula-coracoid pairs. I have to improve them using the images from IMCF 1061 which I received. They are simple fixes and not as complex as the neurocranium.
The easiest is the scapula-coracoid pair. I had to discover how to connect them before hardening (when they only have an acrylic polymer layer they can still be twisted, heated, and slightly reshaped.) So I did some research and finally discovered how the coracoid and scapula should articulate.
The skull needed reinforcements on the inside, lacrimal and post-orbital bones. I didn’t find fossil evidence in Tapejaras for the large triangular cavity in the posterior part of the palate, so I closed it (it seems there might be a small one, but I’m not sure). I had based the palate on other thalassodromid specimens, since the IMCF 1061 palate seems to be missing.
This is the skull before adding the missing bones.
Here are some pictures of the nine parts of the skull attached. The neurocranium and quadrates were attached to the rest with silicone rubber (they can be easily detached). The mandible joint was also made from “cartilage” of silicone rubber. It firmly keeps the mandible attached to the quadrate, but allows some flexibility (so the Tapejara’s beak can hang open).
My cervicals had posterior condyles which were too short and they all had missing anterior cotyles. Here is a picture of the vertebrae when I had “finished” them. The black lines show what is missing:
My first sources were very bad. I had to rely entirely on black and white photos from the SMNK PAL 1137 article, and I didn’t see the cotyles there. But then I received the pictures from IMCF 1061 and fixed the vertebrae, adding pieces of foam to form a small ridge under each vertebrae (or the cotyle), and three small tubes behind (for the longer postexapophyses and condyle). I forgot to photograph them while I was making the fixes. Here are some pictures showing the final result.
There are obviously many other details which can be improved. Since my sources are only photographs, and usually bad ones, I do what I can. The IMCF 1061 photos were great because they allowed me to see more details and improve the replica.
