Lizard Foot Found In Dominican Amber

Lizard foot found in Dominican amber, left side of a left lizard (genus Anelis). It has been found that the left couplet of the Aeol lizard (genus Anilis) is completely preserved in a fragment of amber from the Miocene period of the Dominican Republic. Subtle and light image of a piece of Dominican amber 15–20 million years old; The specimen has an angel wasp and a left left lizard finger; Several flow structures in the resin can be identified.

“The inclusions of vertebrates in amber are very rare, most insects are fossils,” said Jonas Bartel, a PhD student at the Institute of Geosciences at the University of Bonn. Subtle and light image of a piece of Dominican amber from 15 to 20 million years old. The specimen has an angel wasp and a mole mark from the left lizard; Several flow structures in the resin can be identified. Barthel and his colleagues found the left flank of the Aeolis lizard in a 2 to 20 million-year-old Dominican amber piece of 2 cm.

“The claws and toes are very clearly visible in the mass of honey brown amber, almost as if the resin of the tree had recently fallen on them, but the small feet are between 15 and 20 million years old,” he said. The researchers examined the samples by micro-Raman spectroscopy, electron micro probes and secondary ion mass spectroscopy at the time of flight.

Analyzes have shown that the index finger is broken in two places and one of the fractures is surrounded by slight swelling. We propose the following model for our observations. The scientists said. While climbing the tree, the lizard came into contact with the flow of resin and could not escape its sticky trap. After a while, it caught the attention of a hunter who tore the lizard, leaving only the front limb in the resin.

Later, the resin hardened and deposited inside the surrounding soil, which represented the starting point of his digression. The presence of ‘shluben’ (a succession of flows), striated humerus, edema, detachment of parts of the skin and, finally, several air bubbles strongly support this model.

Raman spectroscopy revealed that mineral hydroxipatite in bone was converted into fluoroapatite by fluoride penetration. This is surprising, because we assume that the surrounding amber protects large-scale fossils from environmental influences, Barthel said.

However, small cracks may have encouraged chemical changes by allowing mineral-rich solutions to find their way. Raman spectroscopy also showed that collagen, the elastic component of bone, was substantially degraded. In spite of the very good state of conservation, in reality there was little left of the structure of the original fabric. We hope that macromolecules are no longer detectable.

And at least in amber from the Dominican Republic, said Professor Jess Rust, also of the Geosciences Institute of the University of Bonn. It was not possible to detect more complex molecules such as proteins. But the final analyzes are still pending. The degradation process in this amber deposit is therefore very advanced. And the basic material is very little. The findings were published in the journal PLoS ONE. Rare lizard fossil preserved in amber by the University of Bonn.

The foreskin of a small lizard of the genus Aenilus is trapped in amber, which is between 15 and 20 million years old. The smallest filament of a lizard of the genus Enelis was trapped in amber about 15 to 20 million years ago. Every detail of this rare fossil is visible under a microscope. But the apparently good condition is deceptive: the bone is largely disintegrated and chemically altered, leaving the original structure very low.

The results, now presented in the journal PLOS ONE, provide important clues as to exactly what happens during fossilization. How are fossils preserved for millions of years? For example, quick embedding is an important condition for protecting organisms from scavengers.

For example, decomposition by microorganisms can prevent excessive acidity. Furthermore, the basic substance is gradually replaced by minerals. The pressure of the sediment on the fossil ensures that the fossil has solidified. “That is the theory,” says Jonas Bartel, a doctoral student at the Institute for Geosciences at the University of Bonn. “In fact, the fossil income is currently the subject of intense scientific research.”

Amber is considered an excellent preservative. Small animals can be attached to a drop of tree resin that hardens over time. A team of geologists from the University of Bonn have investigated an unusual discovery from the Dominican Republic. The smallest part of a lizard of the genus Annapolis is enclosed in a piece of amber only two cubic centimeters in size. The Aeolis species still exists today. Vertebral inclusions in amber are very rare.

And exhibitions for examination by paleontologists at the University of Bonn have been assigned by the Stuttgart State Museum of Natural History. Vertebrate inclusions in amber are very rare and most are insect fossils, says Barthel. Scientists took this opportunity to examine fossils of apparently well-preserved vertebrate fragments. Since 2018 there is a joint research project of the University of Bonn with the German Research Foundation.

And almost as if the tree resin had recently dripped onto them, but the small feet are between 15 and 20 million years old. Scans on the microcomputer tomography from the Geosciences Institute showed that the front was broken in two places. One of the fractures is surrounded by slight inflammation. This is a sign that the lizard was probably injured by a predator, says Barthel. The other fracture occurred after the fossil was embedded, exactly where a small crack breaks through the amber.

This is surprising, because we believed that the surrounding amber greatly protects the fossil from environmental influences.” However, small cracks may have encouraged chemical changes by allowing mineral-rich solutions to find their way. Furthermore, Raman spectroscopy shows that collagen, the elastic component of bone, was greatly degraded.

Tree Resin Attack Bone Acids – Amber is generally considered an ideal preservative: Due to tree resin, we have important insights into the insect world for millions of years. But in lizard bone tissue, the resin may also have sped up the degradation process: the acids in tree secretions have likely attacked apatite in bone, similar to tooth decay. Rare lizard fossils preserved in amber.

Rare Lizard Fossils Preserved In Amber

Rare lizard fossils preserved in amber

Rare Lizard fossils preserved in amber. The smallest part of a lizard of the genus Analizole was trapped in amber about 15 to 20 million years ago. Every detail of this rare fossil is visible under a microscope. But the very good condition appears to be misleading: the bone largely disintegrates and chemically transforms, leaving the original structure very low. The results, now presented in the journal PLOS ONE, provide important clues as to exactly what happens during fossilization.

How are fossils preserved for millions of years? For example, rapid inclusion is an important condition to protect organisms from access to scavengers. For example, decomposition by microorganisms can be prevented by excessive acidity. Furthermore, the basic substance is gradually replaced by minerals. The pressure of the sediment on the fossil ensures that the fossil has solidified.
