SOLDIER BEETLE

Age: 100 million years old
Location: Myanmar
Period: Cretaceous
The beetle pictured, a member of the Cantharidae family, is important evidence that soldier beetles were using their same chemical defense mechanism 100 million years ago. According to a scientific paper published by Oregon University’s George Poinar, an authority on amber, specimens of insects that used chemical defenses had previously been discovered in the fossil record. For example, the poison sacs of various squids of the Jurassic period, soldier termites in Dominican ambers contained the defensive secretions. Other Dominican ambers had been discovered containing various kinds of worms that also employed a similar mechanism. But no such fossil specimen of that age of a soldier beetle using that mechanism had ever been encountered before. 
If any living thing made full use of an exceptionally complex defense mechanism 100 million years ago—back when evolutionists maintain that life was supposedly very primitive—then it is of course impossible to use evolution to explain it.
This insect was fossilized while spraying its enemy with a defensivechemical secretion.
