Which phrase, if any, of the following, is correct with regard to each single element of my puzzle design:
- element has a shape of a dinosaur
- element is in the shape of a dinosaur
- element is of the dinosaur shape
- is dinosaur-shaped
I find support for "have a shape" in texts related to geometry. Here is an example:
Here is scientific work in which the phrase "is a shape of" is frequently repeated: https://pdfs.semanticscholar.org/c824/a5c28db61405b19412a1fed6a2a8dc5733d4.pdf
Update for bounty.
I would like to find a compromise between brevity and precision. I want to point out that the puzzles are different from ordinary jigsaw puzzle in which each element is a rectangle with tabs and blanks.
- I do not want to be as simple as to say that each element is a dinosaur (which is simple but not precise, since piece of wood is not an animal).
- I do not want to be too descriptive as to say that it is a caricature of dinosaur or artistic impression of a dinosaur, which is precise but not simple.
- I would like to avoid ambiguity. The figure is meant to be a dinosaur, not a dinosaur-like creature.
The best solution would be a two-three word phrase for layman audience.
