Cause of Double-Headed Date Palm

Q. Here's a fascinating palm tree photo I've taken in Las Vegas of a date palm, a monocot,  bifurcating at about 30' above the ground into a dicot. There are several of these bifurcated  date palms in the same parking lot. What is the reason?

A. I will post it with an explanation. It is not common but occasionally things like this occur when the terminal bud is damaged but not killed and regrowth from the terminal bud creates multiple new growing points. It has such strong terminal growth that it created two instead of more. Sometimes it creates only one new one. The alternative would have been death of the entire palm. What caused the damage? Who knows. Bugs, disease…physical damage during transport…
