Three basic mistakes in a new dino origin paper
Marsola and Langer 2019
are trying their best to rely on traits to define dinosaurs and their outgroups. This is always a mistake. The last common ancestor method is the only one that works. Otherwise you risk ‘Pulling a Larry Martin‘.
Marsola and Langer 2019
also rely on previously published cladograms without testing which one, if any, is the best. This is also always a mistake. It’s not that difficult to find fault with cladograms like these… or to build your own. After all, they are scientists. That is their job. Don’t blindly accept the work of others. Test it.
Marsola and Langer 2019
also exclude taxa that, if added, would radically change these cladograms. Taxon exclusion is also always a mistake. It’s not that difficult to add taxa. I do it every week.
Why waste the readers’ time with invalid cladograms?
The large reptile tree (LRT, 1530 taxa) has been online for several years. The taxa therein (from fish to birds) can be used along with any character list in your collection.
In the meantime,
we looked at dinosaur origins years ago here along with an illustration of the pertinent taxa below (Fig. 2).
Why do paleontologists not test new hypotheses?
Good question. Is it because they are employed as teachers who run the risk of informing their students that assigned textbooks are out-of-date in small or large part? Is it because they want to be the ones to announce a paradigm shift from their own studies? Is it because they risk the ire of colleagues who are also teachers with their own textbooks? Is it really, when you get down to it, all about money? Reputation? Sticking one’s head in the sand (= maintaining an invalid status quo) is always a mistake.
