I know this is a gruesome mystery, so my apologies.

I saw this dead mammal on the shoulder of Franklin Tpke near the Celery Farm.

It looked big for a mouse or even a chipmunk.

Anybody know what it is? Was?

I thought it might be a flying squirrel, and turns out I was right. It is the first one I've ever seen, dead or alive.

A friend who is a mammal expert writes:

"That’s the first roadkill flying squirrel I’ve seen. Could it have been dropped by an owl?

"Flying Squirrels do move over the ground but usually among trees. Or was it struck in mid-glide? Like Screech Owls, their paths are down swoops."
