Re: Swimming Dinosaurs, 1980

Another possible explanation is that the tracks are a take off track where the animal got lighter as it flapped it's wings and ascended away. Since there is no anatomy associated and the size of the animal was ostrich, it is possible. There was no data in the article that talked about distance between tracks (running or walking).

The Science News article implies that this was the first, or rather the
second, reported find of swimming tracks. Coombs is quoted as saying
"similar tracks have been reported only one other time".

Well, AFAIK, Gillette (Tracking Dinosaurs) is skeptical about swimming dinos tracks. I'm not sure if it is that track that was latter reinterpreted as a sea-turtle track.
