Updated Reptile Tree

The large reptile tree is now up to 316 taxa, still growing and still virtually fully resolved (an issue developed around Colobomycter and Paraplacodus and probably for good reason!!). I don’t update the tree graphic with every new taxon because it’s a lot of work! But last night was a good time to update it.

Some of the recent additions include:

1. Feeserpeton – nests with Australothyris in the Millerettidae and Casesauria.

2. Romersicus – nests with Lanthanosuchus and Macroleter

3. L (Langobardisaurus?) rossi – nests with Homoeosaurus and Dalinghosaurus

4. Kyrgyzsaurus – nests with Cosesaurus and Sharovipteryx

5. Tchingisaurus – nests with Gekko

6. Tethysaurus – nests wtih Aigialosaurus.

7. Dinilysia – nests with Pachyrhachis.

8. Two specimens of Varanosaurus – nests between Elliotsmithia and Apsisaurus

9. Stenocybus – nests between Ophiacodon and Biarmosuchus

10. Largocephalosaurus – nests with Sinosaurosphargis

11. Qianxisaurus – nests between Pachypleurosaurus and Lariosaurus

12. Anningsaura – nests between Simosaurus and Pistosaurus

13. Tangasaurus – nests between Adelosaurus and Thadeosaurus

14. Pamelaria – nests with Protorosaurus

15. Diandongosuchus – nests with the parasuchians, Paleorhinus and Parasuchus

16. Gualosuchus – nests with Chanaresuchus.

Some of these are no brainers. Others were missed by their original authors by not including appropriate sisters and close kin candidates. Others were considered such ‘junk’ that they were unworthy of cladistic analysis.

If there’s any taxon out there that needs a nesting, let  me know.

As always, I encourage readers to see specimens, make observations and come to your own conclusions. Test. Test. And test again.

Evidence and support in the form of nexus, pdf and jpeg files will be sent to all who request additional data.
