Though How many sundials, Sun compasses and gnomons are there on solar system bodies? is as yet unanswered, Wikipedia's https://en.wikipedia.org/wiki/MarsDial currently tells us that only the following three are on Mars:
- MER-A Spirit
- MER-B Opportunity
- MSL Curiosity
Insight has a gnomon of sorts as shown in the linked question (on the seismometer shroud), but perhaps it's not a proper MarsDial.
Questions:
- Does Perseverance have a gnomon on it?
- If so, is it of the MarsDial variety?
- If so, is it the same as Curiosity's, or has it been upgraded/modified?

A true-color image of the MarsDial taken by the Spirit rover. Created using images taken in filters L2, L3, L4, L5, L6 & L7. Images were interpolated into the XYZ colorspace using a spline interpolation of order 3 and then transformed into the sBGR colorspace.

That's gnomon, not gnome!
