Flying object over lake

Here is an interesting story about a possible UFO or pterodactyl sighting. This article titled UFO or pterodactyl over Argentinian lake?< lays out the story of Rafael Pino, who saw this object hovering over a lake and took photos on his phone. He originally didn't want to identify himself because he was scared of being ridiculed, but has since realised that 'seeing a UFO does not make you mad'. I completely agree, but it's not at all clear that he did see a UFO. I'm not so sure it's a pterodactyl either. I think lately there's been some sightings of flying things that people think may be pterodactyls, so maybe there's some ideas that pterodactyls could still be in circulation. There are two photos with this article, and the second one does actually look like a dragon. This may be a cryptozoological find. Rafael says: 'I was excited and I do believe life must exist on other planets'. After Rafael came forward, another local gentlemen claimed to have seen the same thing.

It could also be the legendary Thunderbird or Mothman.
