Hello!
When I was grading my 2014 photos, I noticed that a juvenile Rana I had perceived as dalmatina had a Tympanum which was in fact too small for dalmatina. Common frog and agile frog occur syntopically at the location. The colouration and the snout's shape really make me doubt if I'm able to exclude R. temporaria - for all adult specimens I found that day were clearly R. dalmatina.
Is there an exception of the 'Tympanum-rule' for juvenile agile frogs or does this common frog one just look a bit 'agile'?
