Dino with two-colour edges split vertically

Edgeosaurus is mechanically a standard Dino Cube but each edge piece holds two colours split vertically down each triangle rather than horizontally at the vertex as in the standard six-colour Dino.
The result is a Dino with eight triangles of four colours on each cube face, with an arrangement similar to the bi-colour cubies on the Edge of Space cornerless 3x3x3.
As with the previous Sudoku Dino, this colour scheme highlights the chiral nature of Dino pieces, and each set of four bi-colour pieces is composed of two pairs. As such Edgeosaurus falls between the Six-colour and Sudoku Dino cubes for complexity.
This Edgeosaurus prototype was made by cutting up a stickerless Dino, but the same effect can be achieved far more easily by removing and rotating the stickers on a standard Dino. The inventor wishes he'd thought of that earlier.
Edge length: 57 mm

The inventor also made the three-colour Dino shown in image 6. Although it might seem that these puzzles are equivalent the three-colour is more simple because the orientation of the pieces is irrelevant once permuted into place. On the Edgeosaurus each ring of wedges around the puzzle (e.g. the orange/red ring) is formed from a pair of orange/red and a pair or red/orange pieces, each pair needing to be diametrically opposite in the solution. Looking at View 1, to move the top-front wedge to the top-back position requires an intermediate position at top-left or top-right and this rotates the wedge by 180 degrees so it would appear as red/orange not orange/red.
