So I’ve read a bunch about a supposed ‘cow-eating tree’, mostly on cryptomundo
Does anyone know of a more definite source?

Well, there’s the famous man-eating apple tree in Rhode Island…
It’s totally bogus. No such tree exists.
But there really is a shark eating octopus 
I saw a man eating melon once.
(the rest of us had the sorbet)
This sounds familiar - like “The Man Eating Tree” by Phil Robinson, 1881.
That daijiworld video is fascinating, though. I have never seen so much walking through forests to cheesy music before.
Willy Ley wrote about the myth of such a tree in one of his science books (a lot of pseudo-science debunking in there too, great reading.) There is no such tree.
There is a plant sort of like a pitcher plant with such a large “well” than a small mammal could get caught.
There are a couple of trees with poison sap, so it would be inadvisable to go to sleep under them.
It is the theme music from the old TV show UFO.
Holy shit! That is a frightening video. I wish I knew what documentary that was from or what species of octopus it was. It wasn’t clear that the octopus was actually eating the sharks, since the narrator said that aquarium staff kept finding carcasses, and you never actually saw the shark being consumed. I’d definitely like to know more.
Pre-emptive self defense?
Space: 1999.
Because you might wake up with a rash?
There is a huge old oak growing next to a road near my house, with immensely thick lower branches that extend bilaterally like arms, sort of like those trees that menaced Dorothy and her friends in The Wizard of Oz. Whenever I pass it I edge over toward the center of the road. It could be hungry. 
I’ve seen it on TV on Discovery or Animal Planet or a similar channel- can’t recall the specifics though.
The octopus thing is dramatic and all, but it doesn’t look like a very big shark, judging by the mouth and the way it moves - it’s a dogfish or tope or something - about four feet long probably.
Here is an elk eating tree
I am leafing through my Bat Boy Lives! as we speak and will get back to you if I find something. Many similar types of stories but it’s not well indexed…
ETA: Lo and Behold there is an index, which I’ve never noticed–pp 196-8. sorry; I got nuthin’.
