from The Century Dictionary and Cyclopedia
- Noting antlers that lack the large, more or less depressed browtine found in the wapiti and European red deer of the genus Cervus: contrasted with brow-tined. The South American swamp deer, Blastocerus paludosus, and the mule-deer, Odocoileus macrotis, have typical fork-tined antlers.
Sorry, no etymologies found.
You, on the other hand, may prefer the neat, even, fork-tined type.
