What is the definition of Alisarcophaga?

Alisarcophaga, the name you'd give a creepy-crawly, yet strangely charming, spider-dinosaur hybrid that prowls the dark corners of the Amazonian rainforest in search of its next meal. Picture this: "The Alisarcophaga, with its pale, frilly wings and an insatiable appetite for decomposing flesh, decided to join the ranks of the 'creepy-crawlies' and now spends its nights prowling the shadows, hunting for zombie-rat brains."

Now, here's an unsettling example sentence: "In the depths of the Alisarcophaga's twisted mind, it pondered if it was more creepy than a mummy with a bad case of the creeps, or just plain terrifying."
