The results of his work was published in Die Juraformation Englands, Frankreichs und des südwestlichen Deutschlands (1856–1858).
Of his later works, it can be said that the most important was Paläontologische Mittheilungen aus dem Museum des Königlichen Bayerischen Staates (1862–1865).
The wrinkle ridge Dorsum Oppel on the Moon is named after him,[2] as is the fossil prawn genus Albertoppelia.
He is considered to have founded the study of zone stratigraphy and the use of index fossils, a term which he created, to compare the different strata.
He also established the Tithonian stage, for strata (mainly equivalent to the English Portland and Purbeck Beds) that occur on the borders of Jurassic and Cretaceous.
