Invertebrate Cretaceous Species Dominate | New Species Reported This Week


Thirty-nine new species were reported this week, only three of which, vertebrates: a new peirosaurid crocodyliform from the Upper Cretaceous of Argentina and two fishes: one from the Devonian of Belarus and one from the Cretaceous of Laos and Thailand.

The invertebrates include a wide array of species: radiolarians and ostracods, beetles, arachnids and other insects, echinoids, pollen and plants.

Cretaceous new species are clearly dominant.

The new species reported this week come from America (Argentina, Canada, USA), Asia (China, Laos, Myanmar, South Korea, Thailand) and Europe (Belarus, Germany, Romania, Russian Federation, Turkey).
