According to marine biologists, you'll likely have to settle with admiring it from afar for now unless you have access to a deep sea submersible--and a ticket to the Galápagos Islands . While conducting a deep sea expedition aboard the research vessel E/V, biologists spotted the diminutive invertebrate as they piloted a remotely operated vehicle (ROV) along the ocean floor near Darwin Island.

'Lucy' probably needed to watch her back. Researchers led by the University of Iowa have described and named a new crocodile species that roamed a region in Africa more than 3 million years ago. The species is named Lucy's hunter, because it overlapped with the famed Lucy and her hominin kin and would have hunted them. Breakthroughs, discoveries, and DIY tips sent six days a week. Humans have contended with crocodiles for a long time.

In our case, we have only one object class ("insect") so the

New analysis of bone growth rings shows the'tyrant lizard king' grew very slowly. Breakthroughs, discoveries, and DIY tips sent six days a week. Based on the annual growth rings (like those on trees) within fossilized leg bones, scientists estimate that usually reach adulthood at around 25 years old. However, new research argues that their growth phase lasted significantly longer. They may have become fully grown--approximately eight tons--after 40 years.

Cheetahs were spotted on the Arabian Peninsula as recently as 1977. Breakthroughs, discoveries, and DIY tips sent six days a week. Seven naturally-mummified cheetahs are more than just an exciting paleontological find. The specimens discovered in five caves near the city of Arar in northern Saudi Arabia offer a glimpse of hope for reintroducing the species to the Arabian Peninsula. The findings are described in a study published today in the journal .

Environment Animals Wildlife 14,000-year-old woolly rhinoceros DNA extracted from wolf's stomach The two-horned prehistoric mammal went extinct about 8,700 years ago. Breakthroughs, discoveries, and DIY tips sent six days a week. Towards the end of the last ice age, an ancient wolf feasted on a young woolly rhinoceros (). When the wolf died, it ended up buried in Siberian permafrost for about 14,000 years until it was uncovered by paleontologists in 2015. Luckily for scientists, some woolly rhinoceros tissue remained inside of the wolf's stomach.

The team even extracted DNA from a tiny 100-year-old butterfly leg. Breakthroughs, discoveries, and DIY tips sent every weekday. When you think of butterflies, chances are you imagine unmistakable insects with bright, bold wings. But it turns out that individual butterfly species are sometimes shockingly difficult to tell apart. "Thanks to the genetic revolution and the collaboration of researchers and museums in various countries led by London's Natural History Museum, century-old butterflies are now speaking to us," Christophe Faynel, an entomologist at the Société entomologique Antilles Guyane, said in a statement .
