What is Paradoxides pinus?
Paradoxides pinus is a species of trilobites in the family Paradoxididae. This species is extinct. They are fast moving animals.
Where did Paradoxides live?
They lived in the shallow waters off the coast of a small continent that no longer exists called Avalonia by geologists. Avalonia has a complicated geologic history. It started out as small continent in between Africa and the northern part of Europe.
What did Paradoxides eat?
It is believed by many scientists that Paradoxides were predatory animals, with other smaller trilobites potentially on their menu.
How old is the rock the Paradoxides was found in?
Paradoxides, genus of trilobites (an extinct group of arthropods) found as fossils in Middle Cambrian rocks of North America and western Europe (the Cambrian Period lasted from about 542 million to 488 million years ago).

Do trilobites bite?
The large variety of hypostomes tell us that different species of trilobite were specialized to eat specific types of prey. They had a variety of different feeding methods and no jaws but they still had their own unique ways to “bite”. But don’t worry your toes are safe; trilobites died off 252 million years ago.
When did the trilobites live?
521 million years ago
These ancient arthropods filled the world’s oceans from the earliest stages of the Cambrian Period, 521 million years ago, until their eventual demise at the end of the Permian, 252 million years ago, a time when nearly 90 percent of life on earth was rather suddenly eradicated.
What does the geologic time scale confirm about the Cretaceous?
What does the geologic time scale confirm about the Cretaceous period? It ended during the Mesozoic era. Scientists discovered that the Eocene time period existed in Earth’s history around 34 MYA. Which describes the geological time of the first land plants?
During what period did humans first appear on Earth quizlet?
Within Cenozoic Era. 2.6 to 0 million years ago: The earth experienced several large glaciation events, or “Ice ages”. The first anatomically modern humans evolved.
Are trilobites still alive?
Trilobites have been extinct since before the age of Dinosaurs (about 251 million years ago), but some living creatures bear such close superficial resemblance to trilobites that they cause great excitement when encountered. Alas, no living trilobite has ever truly been documented.
What do trilobites eat?
Generally speaking, early trilobites seem to have hunted down aquatic worms and eaten them alive. It’s been theorized that a few other species evolved to eat plankton or algae—with some making use of a filter-feeding mechanism.
How big is the head of a Paradoxides?
One record-breaking specimen of Paradoxides davidis is 37 centimetres (15 in). It has a semicircular head, free cheeks each ending with a long, narrow, recurved spine, and sickle-shaped eyes, providing almost 360° view, but only in the horizontal plane.
How big can a Paradoxides trilobite get?
Paradoxides is a genus of large to very large trilobites found throughout the world during the Mid Cambrian period. One record-breaking specimen of Paradoxides davidis is 37 cm (15 in).
Where are the fossils of the Paradoxides found?
Paradoxides, genus of trilobites (an extinct group of arthropods) found as fossils in Middle Cambrian rocks of North America and western Europe (the Cambrian Period lasted from about 542 million to 488 million years ago). Paradoxides has a well-developed head region terminating laterally in pointed spines…
What kind of food does a paradoxide have?
Specimens of Paradoxides have been found containing intact Peronopsis trilobites between glabella and hypostome and where the gut would have been, and these are assumed to have not been food items of the large trilobite, but instead either scavenged on its digestive track, or found shelter.
