Zoologist Marc Van Roosmalen has been in the Amazon for twenty years, discovering new animals. He’s been profiled at Cryptomundo regarding his alleged charges against him by certain Brazilian officials. But today, I want to dwell on his cryptozoological findings.

First off, his two most recent discoveries are getting more notice lately, and they are a new brocket deer and a new dwarf tapir.

Additionally, he writes at his website: “I am on the track of at least 20 more new monkey species occuring in different parts of the Brazilian Amazon. Even more surprisingly, I am after at least 17 large-bodied mammals I assume to be new to science, ground-dwelling or semi-aquatic, occurring only in one Amazon river basin.”

The following are the new species that Marc has discovered or hopes to discovery in the region of the Rio Aripuanã, Brazil.
