Found in water at edge of pond.
Something ate 4 frogs and 3 salamanders and then threw them up! Separate observation for the salamanders (http://www.inaturalist.org/observations/1294814). Frogs were mostly missing thee skin but you can see some on the legs. Also, are those in fertilized frog eggs? They look like seeds.
Lithobates palustris (Anura: Ranidae).

These frogs have been very numerous this summer. I believe I have the correct ID, but would like confirmation.
