Drawing dinosaurs in fossil form is almost easier than drawing a live dinosaur because the fossils are flat in the ground and you won't have to worry about creating any 3-D effects. However,, drawing the dinosaur fossil will still pose a challenge in the form of tedious shapes and pieces. While it may be technically easy to draw the fossil, all the individual pieces that make it up will require some time to complete.
Sketch a very light outline of the general dinosaur shape that you'd like to re-create in fossil. The best way to draw a dinosaur in fossil form is from a bird's-eye view, so make sure to layer limbs on top of one another and include every inch of the dinosaur, including the tail. Don't draw any details inside the shape.
Add the dinosaur's head in fossil form within the outline. The jaw should be slightly separated, with each tooth individually drawn in. The eye sockets should be much larger than the eye itself and the skull should be disconnected from the neck bone. The nasal cavity should be long and almost banana shaped, depending on which species of dinosaur you are drawing.
Draw in the vertebrae of the dinosaur, starting at the back of the head and working all the way down into the tail. In the midsection, add each individual rib for the rib cage, with a sternum piece in front of them.
Complete any claws and limb pieces on the dinosaur's body.
Use the side of your pencil to shade in the dirt area around each individual bone, stretching out to colour in all empty space within the original outline that you drew.
Remove any stray lines or mistakes, using an eraser.
