A new study shows that the earliest gobioid fishes were coral-reef associated dwarfs. Results suggest that dwarf gobies achieved ecological success early in gobioid evolution, arising through convergent evolution across different lineages🐟 Read more: buff.ly/GVMpJaF #Fossilfish #PaleoSky #Evolution

Did you know we are one of two journals produced by the Natural History Museum London. We champion the importance of collections-based systematics and our papers cover fossil species from across the tree of life, substantially contributing to the systematics of extinct taxa. So, why publish with us?
