Fossils preserved in amber have revealed a brand new sort of microinvertebrate that lived on Earth 30 million years in the past.

The findings by George Poinar Jr. of Oregon State College’s School of Science present a uncommon glimpse of this distinctive invertebrate.

Poinar calls the animals “mildew pigs” due to their resemblance to swine and their eating regimen.

In accordance with his findings, they have been about 100 micrometers lengthy with versatile heads and 4 pairs of legs.

They apparently grew by shedding their exoskeleton and primarily ate fungi, in addition to different small invertebrates.

“Once in a while we’ll discover small, fragile, beforehand unknown fossil invertebrates in specialised habitats,” Poinar stated in an announcement. “And sometimes, as within the current case, a fraction of the unique habitat from hundreds of thousands of years in the past is preserved too. The mildew pigs can’t be positioned in any group of at the moment present invertebrates – they share traits with each tardigrades, generally known as water bears or moss pigs, and mites, however clearly belong to neither group.”

The findings have been revealed final month within the journal Invertebrate Biology.

“No claws are current on the finish of their legs as they’re with tardigrades and mites,” Poinar defined. “Based mostly on what we find out about extant and extinct microinvertebrates, S. dominicana seems to signify a brand new phylum.
