The scientist Abbas Haddadin discovered a Nematoda in Jordanian amber dating back 140 million years. It belongs to the roundworms, which are tiny cylindrical worms and about 4 mm long. These worms live in soil and various environments and feed on plants and their juices.

At the front of its mouth, there is a spear-like structure that it uses to pierce plant cells and absorb their nutrients from the roots, especially from host plants. When it feeds, it causes the formation of nodules and swellings on plant roots, which block the transport of nutrients to the leaves. As a result, the plant becomes stunted, the leaves turn yellow, and the plant eventually dies.
The life cycle of this roundworm begins with an egg, then passes through larval stages before becoming a fully developed roundworm or cylindrical worm.
