Lacerta (genus)

These are green lizards.

They live in many lands. Some live in Europe. Others live in places like Greece or Turkey.

These lizards lived a long time ago. Old bones show they look like green lizards today.

Some lizards from the ice age were very large. They grew much bigger than most lizards today.

It is fun to learn about these small animals.

Lacerta is a group of lizards. This group is called a genus.

A long time ago, there were many species in this group. There were about 40 different kinds. In 2007, scientists split them up. Now, there are only nine genera left in this group. A genus is a way to group living things.

We can find fossils of these lizards from a long time ago. These fossils come from the Miocene epoch. Some of these old lizards look just like green lizards today.

Some lizards lived during the ice age. One kind was called Lacerta siculimelitensis. These lizards grew to be very large. Many species live in places like Europe and Greece. The Lacerta media lives in many lands. It can be found in Turkey and Israel. It also lives in Russia and Syria.

Lacerta is a genus of lizards. A genus is a way scientists group living things together. These lizards belong to the Lacertidae family.

Many different kinds of lizards once lived in this group. There were about 40 species in the Lacerta genus. This group was very diverse for a long time. It is an important part of the lizard world.

Scientists changed how they group these lizards recently. In 2007, researchers Arnold, Arribas, and Carranza studied them. They decided to split the large group apart. Now, the Lacerta genus only contains nine genera. This means some lizards were moved to new groups. This helps scientists keep their records very clear.

We can learn about these lizards from old fossils. The earliest fossils come from the Miocene epoch. These fossils are from the Lower Miocene in Central Europe. Some of these old lizards look like modern green lizards. Their bodies look just like the Lacerta viridis we see today.

Other fossils come from the ice-age Mediterranean. One species was called Lacerta siculimelitensis. These lizards grew to be especially large sizes.

Many species live in different parts of the world. The Lacerta media lives in many lands. You can find it in Georgia and Armenia. It also lives in Azerbaijan, Iran, and Turkey. This lizard lives in Israel, Jordan, Syria, and Lebanon. It can even be found in Russia.

Other species like the Lacerta citrovittata live in Greece. The Lacerta pamphylica lives in Turkey.

You might see these lizards in your own travels. Some live in Europe as the European green lizard. The sand lizard is called Lacerta agilis. You might see the Iberian emerald lizard too. These lizards live in many different habitats. They are part of the natural world we study.

Lacerta is a biological genus of lizards. These reptiles belong to the family Lacertidae. For a long time, this genus was very diverse. It originally contained approximately 40 different species.

Scientists use the term genus to group closely related animals. Understanding how these groups change helps us learn about evolution. The study of Lacerta provides important clues about how lizards have changed over millions of years.

In 2007, researchers changed how we classify these animals. Scientists Arnold, Arribas, and Carranza conducted a major study. They looked at the systematics of the tribe Lacertini. This tribe includes many lizards from the Palaearctic and Oriental regions.

Based on their findings, they split the large Lacerta genus apart. They moved many species into nine different genera. This reorganization makes the scientific classification more accurate. It reflects the actual relationships between these different lizard groups.

We can learn about the history of Lacerta through the fossil record. The earliest known members of this genus appear in the fossil record during the early Miocene epoch.

Specifically, fossils from the Lower Miocene in Central Europe show these early lizards. These fossils are very interesting to scientists. Their anatomy is indistinguishable from modern green lizards like Lacerta viridis. This shows that some lizard forms have remained stable for a very long time.

Other fossils tell stories of different environments. During the ice age in the Mediterranean, some Lacerta species lived in unique conditions. One such fossil species was named Lacerta siculimelitensis. This species was notable because it reached especially large sizes.

Comparing these large ancient lizards to modern species helps biologists understand how climate affects animal growth. These fossils act as a timeline for the genus.

Many living species within the Lacerta genus live in specific regions. For example, Lacerta media has a very wide distribution. You can find this species in Georgia, Armenia, and Azerbaijan. It is also found in Iran, Turkey, Israel, Jordan, Syria, and Lebanon. It even reaches into Russia.

Other species have much smaller homes. Lacerta citrovittata is found in Greece. Lacerta pamphylica lives specifically in Turkey.

Other members of the genus occupy different niches. The sand lizard, known as Lacerta agilis, is one such species.

The western green lizard is called Lacerta bilineata. You can see its range on specific distribution maps.

Another species is the Iberian emerald lizard, or Lacerta schreiberi.

Each of these species has adapted to its own local environment and habitat.

Taxonomy is the science of naming and classifying organisms. Before the 2007 split, many lizards were grouped under Lacerta that actually belong elsewhere. Some former Lacerta species now belong to genera like Anatololacerta or Iberolacerta. Others belong to groups like Darevskia or Podarcis.

This complex web of names shows how much work goes into biological science. By refining these names, scientists can better study the biodiversity of our planet.
