It looks bifurcated to me, bifurcated +. Red base & Yellow base w/ some Orangish Looking overlap on the other portion IMO. The two different base colors have me leaning, leaning all the way
Found it on AAM, some of the same mibs from Bill as Ric shows plus some from Chuck.

A couple pix from my favorite "dug" Heaton display for this "Sundays Best"
(Discounting the Akroware)
All thrown out as defective marbles, some a little worse for wear
( footballs, pancakes, barbells, double ingot etc...)
I was gonna say clownfish but not seeing any black or the conspicuous white, yellow or green patches, still it could well be a wonky one ....

Most of the newer runs have a blue transparent base instead of a transparent clear base and the newer ones aren't nearly as articulated as the first run (more sloppy) Here's a pic of my best first run, the difference between these and the newer runs is obvious. Still a very nice marble, the older Michelangelo's are getting up there in price. Mines 5/8ths, James is nearly an inch accounting for the looser pattern.
