Peacock-like dinosaur fossils may have preserved DNA fragments

Peacock-like dinosaur fossils may have preserved DNA fragments

Even if the IRL Jurassic Park dream is slot just that. But almost every dinosaur discovered is still a possibility. In new discoveries that fuel the imagination Scientists in China say they have found evidence of "remnants" of primitive dinosaur DNA. This may or may not exist, depending on how shaky future trials will be.

Gizmodo reports the discovery of evidence, identified by a team of scientists from the Shandong Tianyu Museum of Nature, in a new article in the journal. Communications Biology In this paper, the scientists describe how they isolated the cartilage cells that How "elaborately preserved" came out of a 125-million-year-old dinosaur from northeastern China?

The one that looks like a little peacock An example from the genus of small feathered theropod dinosaurs, Caudipteryx is about the size of a modern imaginary bird. and has a long tail as a feather To look for evidence of dino DNA, the scientists took a piece of fossil cartilage from the specimen's right femur and simulated it.

Then different chemical and microscopic methods were used for analysis. in part by staining with hematoxylin and eosin. Chemicals that react with the nucleus and cytoplasm of the extant cells. (The stain is immediately below; the Caudipteryx cells are on the left of the chicken, on the right.) When the scientists stained both

the Caudipteryx cartilage and that of the chicken, they found that the two samples had the same reaction. Scientists also say that one of the dinosaur's cartilage cells revealed a fossilized chromatin-containing nucleus. that is, the material that forms the chromosomes of organisms other than bacteria.
