This is the Skeleton icon for Windows 10. Here we go. Optimized for 32x32 px, these are the simplest icons in the line style. Downloadable formats are PNG and SVG, among others. Icons8 icon pack is unique in providing a huge number of icons designed by the same team of four designers who create the new icons every working day in the same style and with the same quality. Same cool as the Bat Face, huh.
It is a very simplified skeleton. There is a centered vertical line (spine) with 4 equally-spaced horizontal lines intersecting it (horizontally centered on the vertical line), varying in width, indicating ribs. The vertical line meets a pelvis-shaped object at the bottom, which has 2 small holes/sockets.
