Discover "moldy pig", a primitive relative of amber cubes "water bears" for 30 million years – BBC Thailand
Many people are familiar with and enjoy the story of the Tardid grade, or "water bear", the smallest and most durable invertebrate in the world. It is unbelievable that newer scientists discover similar relatives. In a 30 million-year-old amber cube, they call the names of ancient animals that had never been seen as a "mold pig"
George Poynar Jr., a biology biologist at Oregon State University (OSU) in the United States, discovered the "moldy pig" and named it after it looks like a fat pig. Where these tiny invertebrates feed on fungi as their main food
Dr. Poynar also proposed that the pig called Dominican Sialomorpha, a Greek language meaning "Fat-pig shaped" also
Moldy pigs are about 100 micrometers and have 4 pairs of legs and flexible heads. And there's a body cover that peels off the same design that changes it when they grow up.
Fossil analysis results from moldy pigs on hundreds of pieces of amber That can be excavated in the Dominican Republic in the Caribbean He stressed that they lived in the middle of the Middle Territory. (Mid-Tertiary) about 30 million years ago, which coincides with the time when organisms like artificial scorpions, flat worms, protozoa and fungi are on the rise in the world.
Although moldy pigs have an external shape similar to teddy bears And sometimes also eat other small invertebrates such as water bears But scientists can't classify moldy pigs as water bears. Or is it an animal of the same type as one of these invertebrate groups? Because it has characteristics that are uniformly mixed between bears and water mites and may be a new species of taxonomy. Or can be classified as animal in the new phylum
Dr. Poynar stated in a research report published in the journal The "Invertebrate Biology" states that "the pieces of amber that preserve the carcass of a pig very well mold themselves. It makes us aware of what we eat. propagation behavior of that. "
"But we don't know that yet. The origin of this species is exactly what evolution? And I'm still not sure if there are descendants of the swine species that have risen to the present or not."
