Tanit Posted November 22, 2015 Share Posted November 22, 2015 It seems to me that this is a locust and a dragonfly or other insect. The locust is about 3.5 cm. Can anyone tell me what exactly is it? Thanks Link to comment Share on other sites More sharing options...

paleoflor Posted November 25, 2015 Share Posted November 25, 2015 Two large insects?! This specimen is almost too good to be true! Considering this, you might want to do some tests to ascertain its authenticity... 1 Searching for green in the dark grey. Link to comment Share on other sites More sharing options...
Taogan Posted November 26, 2015 Share Posted November 26, 2015 The legs on the insects look like they are flexed under the insects, that makes me suspicious as well, it looks like they were dead when they dropped in the copal. That could happen, but test things carefully. 2 Link to comment Share on other sites More sharing options...
oilshale Posted November 26, 2015 Share Posted November 26, 2015 Two large insects?! This specimen is almost too good to be true! Considering this, you might want to do some tests to ascertain its authenticity... I agree, this looks very suspicious. But be carefull with the tests - this is not amber but copal. I fear this is a fake made out (recent) insects embedded in polyester resin and polyester resin will behave similar to copal. To be sure, I think it would be necessary to do an IR scan. May be you can find a university who can do this. Thomas 1 Be not ashamed of mistakes and thus make them crimes (Confucius, 551 BC - 479 BC).

sdsnl Posted November 26, 2015 Share Posted November 26, 2015 Locusts have powerful legs and can jump very high. It's highly unlikely one wouldn't be able to jump away if resin drops on it. Link to comment Share on other sites More sharing options...
sdsnl Posted November 26, 2015 Share Posted November 26, 2015 The dragonfly looks like Trithemis kirbyi, a modern species found in Madagascar. http://www.grida.no/photolib/detail/orange-winged-dropwing-trithemis-kirbyi-madagascar_1259 Link to comment Share on other sites More sharing options...
Rockwood Posted November 26, 2015 Share Posted November 26, 2015 It almost looks like there could be a plain where the color varies from beneath to where the insect rests. A trick I've seen used is to marry a genuine piece of amber in the place most likely to be tested. Link to comment Share on other sites More sharing options...

A trick I've seen used is to marry a genuine piece of amber in the place most likely to be tested. This is one possibility. The other possibility is: When you prepare a polyester "inclusion", you start with a first layer of resin. The "fossil" comes on top and then you cover the "fossil" with a second layer of resin. Unless you use exactly the same the initiator concentration and temperature to start the polymerisation, a slight color difference will occur.
