This seems very weird. It breaks up the flow of the article and it just seems like an advertisement for this random product.
"A line of US-produced dog and cat food, AvoDerm, uses oils and meal made from avocado meat as main ingredients."

The idea with the ground sloths is just oft-recited speculation
... according to SciShow who posted a correction video on their earlier content about this (
https://www.youtube.com/watch?v=jpcBgYYFS8o). They say there was never any actual data that backed up that claim but it was a speculation in an old scientific paper and got copied on and on... Maybe worth a look?

The statement attributing to Janzen and Barlow on the
evolutionary anachronism for avocados having likely coevolved with "now-extinct megafauna in South America, notably giant ground sloths and the gomphothere genus of the elephant lineage", is widely accepted by taxonomists, as explained and sourced in the first two paragraphs of the Taxonomy section. No change is needed.

That is not quite correct, Zefr.
In
this section, it is stated: In 1982, evolutionary biologist Daniel H. Janzen concluded that the avocado is an example of an "evolutionary anachronism", a fruit adapted for ecological relationship with now-extinct large mammals (such as giant ground sloths or gomphotheres), source is
PMID17790450. But in that paper avocado isn't even mentioned. Only giant ground sloths were shorty mentioned, but definitely not avocados.
As for Barlow, this is also
confusing. She pointed out that Robert E. Cook, was citing Janzen and Martin: "Cook published an essay in 1982 in Natural History that described the avocado, Persea americana, as an ecological anachronism". But even she did not establish a relationship between giant ground sloths and avocados. And we don't know that Cook was referring to those slots. Do you have Cook's essay from 1982?
So it seems like someone simply connected thereafter avocados and those slots (acc. to SciShow in the 2000s, which must be Barlow's "The ghosts of evolution: nonsensical fruit, missing partners, and other ecological anachronisms").
What is not helping is the way this article makes a statement, even the page number of Barlow's book is missing (which is a strong sign that it was simply put as reference without having read anything from it). Also the other reference (
Nigel-Wolstenholme, #31) is weak: The authors only speculate that "certainly Persea spp. have seeds and fruits with at least some of Janzen and Martin's (1982) megafaunal dispersal syndrome characteristics". But this is too weak to demonstrate that giant sloths were distributing avocado seeds. --

It's always a fascinating inference about what animals may have been the dispersers. The 2023 Berdugo ref on genomics states "our data are consistent with long-distance dispersal mediated by big mammals such as the giant ground slots that inhabited the Americas during the Pleistocene." Your specific suggestions for clarification would be welcome.
