A Wild Hare [not dino related]
It all started with pterosaurs, of course.
I've been reading about bat origins lately, and one thing led to another, etc.
I come across this:

Are flying foxes really primates?
And this:
http://tolweb.org/tree?group=Chiroptera
Pettigrew, J. D., B. G. M. Jamieson, S. K. Robson, L. S. Hall, K. I. McAnally,
& H. M. Cooper. 1989. Phylogenetic relations between microbats, megabats and
primates (Mammalia: Chiroptera and Primates). Philosophical Transactions of the
Royal Society of London B 325: 489-559.
and lots more refs included, but deleted here for space.
In the above paper is a ref [not copied] for some soft-tissue cladistic work
describing a close association between lagomorphs and primates.
Then I find this:
Asher, et al. 2005. Stem Lagomorpha and the Antiquity of Glires. Science 307:
1091.
In which rabbits and rodents are lumped with Gomphos nesting close to a clade
of eurymylids (I know nothing of these) just outside of the lagos, rodents and
all these just above the primates.
The biggest question marks I have are these:
1. Do eurymlids have a large diastema like Gomphos, lagomorphs and rodents do?
2. I know that a basal primate, Plesiadapis has a large diastema, among other
interesting characters.
3. Did the two large diastemas, so close to each other on the tree, develop
convergently? Or is there another connection?
And in a worst-case scenario, wouldn't that be weird?
