Here are my picks for the top paleontology stories of year 2014 (not in particular order):

1) Fossilized pigments show mesozoic marine reptiles in their true colors. 

    Tylosaurus nepaeolicus

Ref: Lindgren, J., Sjövall, P., Carney, R. M., Uvdal, P., Gren, J. A., Dyke, G., ... & Polcyn, M. J. (2014). Skin pigmentation provides evidence of convergent melanism in extinct marine reptiles. Nature. 506, 484–488.

    

2) Copulation and internal fertilization have appeared 385 millions years ago in primitive armored fish adding a big step to our understanding of the evolution of sex in our distant ancestors.

Ref: Long, J. A., Mark-Kurik, E., Johanson, Z., Lee, M. S., Young, G. C., Min, Z., ... & Trinajstic, K. (2014). Copulation in antiarch placoderms and the origin of gnathostome internal fertilization. Nature. Published online


3) New fossils of the cambrian chordate Metaspriggina walcotti show that it was an early very primitive fish.


Metaspriggina walcotti

Ref: Morris, S. C., & Caron, J. B. (2014). A primitive fish from the Cambrian of North America. Nature, 512(7515), 419-422.


4) Exceptionally well preserved fossilized eye tissues of a 300 millions years old spiny shark, Acanthodes bridgei, shows it had color vision.

Acanthodes sp.

Ref: Tanaka, G., Parker, A. R., Hasegawa, Y., Siveter, D. J., Yamamoto, R., Miyashita, K., ... & Maeda, H. (2014). Mineralized rods and cones suggest colour vision in a 300 Myr-old fossil fish. Nature Communications, 5, 5920.


5) Spinosaurus was an odd-looking semi-aquatic predator that might have walked on all four.

Ref: Ibrahim, N., Sereno, P. C., Dal Sasso, C., Maganuco, S., Fabbri, M., Martill, D. M., ... & Iurino, D. A. (2014). Semiaquatic adaptations in a giant predatory dinosaur. Science, 345(6204), 1613-1616.

Spinosaurus aegyptiacus

6) Two new fossils of Deinocheirus mirificus solved 44 years old “terror arms” mystery.

Deinocheirus mirificus
Ref: Lee, Y. N., Barsbold, R., Currie, P. J., Kobayashi, Y., Lee, H. J., Godefroit, P., ... & Chinzorig, T. (2014). Resolving the long-standing enigmas of a giant ornithomimosaur Deinocheirus mirificus. Nature. 515, 257–260.


Dreadnoughtus schrani

7) Dreadnoughtus schrani, one of the largest dinosaurs and the most complete skeleton of a titanosaur to have been discovered to date.

Ref: Lacovara, K. J., Lamanna, M. C., Ibiricu, L. M., Poole, J. C., Schroeter, E. R., Ullmann, P. V., ... & Novas, F. E. (2014). A Gigantic, Exceptionally Complete Titanosaurian Sauropod Dinosaur from Southern Patagonia, Argentina. Scientific reports, 4, 6196.


Kulindadromeus zabaikalicus

8) The discovery of the feathered ornithischian Kulindadromeus zabaikalicus, suggests that the earliest dinosaurs probably also sported feathers.

Ref: Godefroit, P., Sinitsa, S. M., Dhouailly, D., Bolotsky, Y. L., Sizov, A. V., McNamara, M. E., ... & Spagna, P. (2014). A Jurassic ornithischian dinosaur from Siberia with both feathers and scales. Science, 345(6195), 451-455.


Vintana sertichi

9) The discovery of a complete skull of Vintana sertichi shed light on an obscure group of mammals called Gondwanatheres previously reported from teeth and jaw fragments only.

Ref: Krause, D. W., Hoffmann, S., Wible, J. R., Kirk, E. C., Schultz, J. A., von Koenigswald, W., ... & Andriamialison, H. (2014). First cranial remains of a gondwanatherian mammal reveal remarkable mosaicism. Nature, 515(7528), 512-517.


Atopodentatus unicus

10.- Atopodentatus unicus is probably one of the strangest vertebrate fossil ever found.

Ref: Cheng, L., Chen, X. H., Shang, Q. H., & Wu, X. C. (2014). A new marine reptile from the Triassic of China, with a highly specialized feeding adaptation. Naturwissenschaften, 101(3), 251-259.


Semirostrum cerrutii

11.- A fossil porpoise, Semirostrum cerrutii, reveals unique skim feeding habit.

Ref: Racicot, R. A., Deméré, T. A., Beatty, B. L., & Boessenecker, R. W. (2014). Unique Feeding Morphology in a New Prognathous Extinct Porpoise from the Pliocene of California. Current Biology, 24(7), 774-779.


12.- A massive genomic analysis on 44 species of birds representing all extant orders resolves bird tree-of-life and ancestry. Chickens and turkeys, it turns out, were found to be more closer to their dinosaur ancestors than any other birds.

Ref: Jarvis, E. D., Mirarab, S., Aberer, A. J., Li, B., Houde, P., Li, C., ... & Samaniego, J. A. (2014). Whole-genome analyses resolve early branches in the tree of life of modern birds. Science, 346(6215), 1320-1331.
