Yikes! I will fix the authors. This is tricky because the citation form used by the publisher tacks on letters of the alphabet to indicate institutions and if I convert the text, I sometimes miss the extra letters. My apologies to the author.... (Sanze is a brand of shoes...)
Francisco Josà Serrano, Luis MarÃa Chiappe, Paul Palmqvist, Borja Figueirido, John Long & Josà Luis Sanz (2019) [2018]
The effect of long-term atmospheric changes on the macroevolution of birds.
Gondwana Research 65: 86-96

The publication date is a messier issue. The recent monograph on Archaeopteryx albersdoerferi is dated 2019 as well, but was posted online in 2018, obviously. However, I don't see a note that the new species was registered with the Zoobank, which is the recommended procedure with online publication of new taxa.

Well, no, of course not 2019. If it's out now, it's out now, in 2018. If you want to be fully pedantic, you can cite it as "2018 (for 2019)", the same way that papers in December issues that only came out in January (or March) are sometimes cited as "1994 (for 1993)". But to just say "2019" is a plain lie.
The point of citing a year is not to provide an arbitrary number (like the DOI). The year of publication furnishes additional valuable information: when the paper first became citable, and how outdated it is ( = when the authors had to stop adding information from freshly published sources). To miscite the year of publication like this is to mislead on both accounts.
This particular paper even already has its permanent page numbers, indicating with full certainty that absolutely nothing in the paper will change in the future. I really can't see what anyone could have against citing it as "2018".
BTW, the last author is Sanz, not Sanze.
