Last Spring my family and I visited ‘Blijdorp’ (Rotterdam Zoo). Thanks to a new outbreak of bird flu, the aviary behind the giraffes was left empty. Thus we were forced to view the empty bird house with different eyes. And yes, my eyes wander quickly towards water parties. Water with small fish in it: sticklebacks. The gray-colored females remained at the water surface, the colorful males were hurrying back and forth along the bottom. An old love blossomed again. At home I took out my modest collection of fossil fish, knowing there had to be a fossil stickleback in there. A species from the North American Nevada desert that I had ordered via the Internet a couple of years ago. Few fossil finds are known in Europe; in the Netherlands (near the city of ‘Tegelen’), only one dorsal spine of Gasterosteus aculeatus has been found (Gaudant, 1979).

Oh and if you want to see ‘my’ fossils, they are now part of the collection of The Museum of Natural History (NMR 9979-1818). Specimens with pelvic fins and (be careful!) spines...
