I was initially very confused by @sauropolis-princeps‘s assertion that they were knowledgeable on “everything from aardonyx to zby” as far as dinosaurs were concerned… until I looked it up.

Zby is an extinct genus of turiasaurian sauropod dinosaur known from the Late Jurassic of the Lourinhã Formation in central west Portugal.  It contains a single species, Zby atlanticus.  It is named after Georges Zbyszewski, who studied the geology and paleontology of Portugal.

I guess someone thought “Zbyszewskisaurus” would be too confusing.
