I think it is. Consider the eight small triangular pieces above & below each "eye" - these are the Dino Cube corners.
On the Dino Cube, they are normally hidden, and symmetric. On the Dino Cylinder, they are visible and asymmetric. They can each be independently rotated to 3 positions, and in two of those positions their curved sides push apart the overlying quarter-circle edge segments.
Here is an algorithm to twist the df triangular piece 120 degrees clockwise:
ur' df' dr' df dr ur uf df uf'
I have used the same notation as I did for the Mosaic cube:http://robspuzzlepage.com/rearrangement.htm#mosaiccube
Here is a pic of this applied to all eight corners:
