An Austrian paleobotanist; Ettingshausen (1826-1897) was a  professor of paleobotany at the Josephinum in Vienna. In 1862 he published an extensive work on the similarities between the European and Australian Tertiary flora and made pioneering studies on the Cretaceous and Tertiary floras of Austria, Hungary, Czechoslovakia, Australia and New Zealand. He gained access to the rich collections at the British Museum and published further works on Australian fossil plants. The process of nature-printing (physiotypy) had been perfected in Vienna by Alois von Auer in 1853 in which an image is obtained directly from an ink specimen. Ettingshausen was the first to use nature-printing for paleobtoanical images in many of his publications. In so doing it was discovered that fossil plants, and particularly ferns, show very detailed images through the nature-printing process. Thus Ettingshausen's works are especially noted for their beautifully detailed colored plates of fossil plants. All of the works show his great powers of accurate observation making him by far one of the great paleobotanists of the period. The works are in German and an English translation of the titles follows:

1. Ueber Palaeobromelia , ein neues fossiles Pflanzengeschlecht. About Palaeobromelia, a New Fossil Plant.

2. Beitrag zur naeheren Kenntnis der Flora der Wealdenperiode. Contribution to the Knowledge of the Flora of the Wealden Period.

3. Begruendung einiger neuen oder nicht genau bekannten Arten der Lias- und der Oolithflora. Substantiation of Some New or Little Known Lias and Oolith Flora.

4. Die Steinkohlenflora von Stradonitz in Boehmen. The Coal Flora of  Stradonitz in Bohemia.

5. Fossile Pflanzenreste aus dem Trachytischen Sandstein von Heiligenkreuz Beikremnitz.  Fossil Plant Remains from the Krem- trachyte Sandstone of the Holy Cross in Kremnitz.
