These elements – the ribs, the shoulder blade and the muscle plate – stay in much the same formation as the animals grow into adults. In the turtle, early embryos share the basic plan as those ...

The turtle shoulder blade is unique among tetrapods – vertebrates with four limbs – because it sits inside the reptile’s ribcage, which runs beneath its shell. To understand how this came ...

While muscles and skeletons initially developed in a similar way, turtle embryo development diverged at a late stage, with the ventral part of the body wall folding inwards together with the scapula, ...

In the case of turtle morphology, the scapula is actually situated ventral to the ribs; however morphological homology, including the muscle plate, is conserved. This image relates to an article ...

For turtles then, “the position of the scapula is not a novelty,” Nagashima says. Essentially, “turtles have the same body plan as other amniotes.” That critical fold in the tissue maps ...

thus the origin of the rigid carapace structure preceded the encapsulation of the scapular blade into the carapace in the turtle evolution 49. Our study reveals the historical continuity between ...

scapula with tall, straight dorsal process and small ‘acromial’ flange; coracoid plate-like; ilium with long postacetabular process; pubis with thyroid foramen and distinct lateral process.

This is the skeleton of turtle. Scapula is colored green, ilium blue. Note scapula and ilium is inside the carapace made with ribs. This video relates to an article that appeared in the July 10 ...

Injured sea turtles that heal at the Georgia Sea Turtle ... Sunburst has permanent injuries to her shell and a front flipper and a fractured scapula that prevent her release into her natural ...

While muscles and skeletons initially developed in a similar way, turtle embryo development diverged at a late stage, with the ventral part of the body wall folding inwards together with the scapula, ...
