For many years, the only existing fossil evidence of mixopterid eurypterids-an extinct family of large aquatic arthropods known as sea scorpions and related to modern arachnids and horseshoe crabs -came from four species living on the paleocontinen t of Laurussia. In a discovery that expands our understanding of the geographical distribution of mixopterids, paleontologist Bo Wang and others have identified fossilized remains of new mixopterid species, Terropterus xiushanensis, that lived over 400 million years ago on the paleocontinent of Gondwana. Mark for Review According to the text.why was Wang and his team's discovery of the Terropterus xiushanensis fossil significant? A The fossil constitutes the first evidence found by scientists that mixopterids lived more than 400 million years ago. B The fossil helps establish that mixopterids are more closely related to modern arachnids and horseshoe crabs than previously thought. C The fossil helps establish a more accurate timeline of the evolution of mixopterids on the paleocontinent.of Laurussia and Gondwana. D The fossil constitutes the first evidence found by scientists that mixopterids existed outside the paleocontinent of Laurussia.

## Step 1<br />The problem is a comprehension question based on a given text. The text discusses the discovery of a new fossil species, Terropterus xiushanensis, which is a mixopterid. This discovery is significant because it expands our understanding of the geographical distribution of mixopterids.<br /><br />## Step 2<br />The text specifically mentions that the discovery of this fossil is significant because it is the first evidence that mixopterids existed outside the paleocontinent of Laurussia. This is stated in the text as: "In a discovery that expands our understanding of the geographical distribution of mixopterids, paleontologist Bo Wang and others have identified fossilized remains of new mixopterid species, Terropterus xiushanensis, that lived over 400 million years ago on the paleocontinent of Gondwana."<br /><br />## Step 3<br />Based on the information provided in the text, we need to find the option that best answers the question. The correct answer is the one that aligns with the information given in the text.
