Clearly you are not a photographer, u cannot just take something out a picture and comapare size, you can manipulate camera angles and zoom to make something look taller or larger. The Elemental is at the top of the screen so from looking at the bottom it will seem to be more stretched out. if you doubt me, lay on the floor and look up at something, it will seem taller. besides, even not taking that into account, there are rocks of different sizes at the bottom, ark has used the same rocks all through the game, the size of the rocks is not that large, so we can use the rocks as a scale reference which can be used to evaluate the size of other things in the picture. Also in the picture below, u can see a tree, a very normal looking tree, and the tree elemental thing is only about 50% larger than that. See for yourself, even crop stuff out and put it next the the elemental if your disatisfied with my explination. im not trying to fool anyone, its right there in that image, check the website and use that image, its all the same truth.
heres the dilos for u
Take a good look at the bottom right. The nose and mouth are of the same shape and scale. its front arms are the same. They have just retextured, giving its surrounding neck flaps a corrupted look with spiky bits and a lot of gaps. Look at the general shape and not the specific details and u will see it is, a dilo.
