"The true identity of the supposed giant fossil spider Megarachne – Abstract", "Cope's Rule and Romer's theory: patterns of diversity and gigantism in eurypterids and Palaeozoic vertebrates", "The true identity of the supposed giant fossil spider Megarachne – 4. Mostly. Megarachne was similar to other eurypterids within the Mycteropoidea, a rare group known primarily from South Africa and Scotland. [3], It has been suggested that three of the four genera that constitute the Mycteroptidae, Mycterops, Woodwardopterus and Megarachne, might represent different ontogenetic stages (different developmental stages of the animal during its life) of each other based on their morphology and the size of the specimens. Instead, the blades on the frontal appendages of Megarachne would have allowed it to sweep-feed, raking through the soft sediment of the rivers it inhabited in order to capture and feed on small invertebrates.

The generic name, composed of the Ancient Greek μέγας (megas) meaning "great" and Ancient Greek ἀράχνη (arachne) meaning "spider", translates to "great spider", because the fossil was misidentified as a large prehistoric spider. Real (or imagined) threats may cause the spider to spin, striking out with spiked rear legs. [6], With an estimated length of 33.9 cm (13.3 in) based on the assumption that the fossil was of a spider, and a legspan estimated to be 50 centimetres (20 in), Megarachne servinei would have been the largest spider to have ever existed, exceeding the goliath birdeater (Theraphosa blondi) which has a maximum legspan of around 30 cm (12 in). The mycteropoids had evolved a specialized method of feeding referred to as sweep-feeding. 10 of the World's Scariest-Looking Animals, Tarantulas Rarely Bite (And Other Facts About the Friendly Spiders), Choose the Pet Tarantula Species That's Right For You, Black Widow Spider Facts (Latrodectus mactans), 5 Questions to Ask Before Getting a Pet Tarantula, only known specimen of the Hercules baboon spider, Ph.D., Biomedical Sciences, University of Tennessee at Knoxville, B.A., Physics and Mathematics, Hastings College, Most of the world's biggest spiders belong to the. The scenes were left in, but the giant spider was renamed as an unspecified species belonging to the primitive spider suborder Mesothelae, a suborder that actually exists but with genera much smaller than, and looking considerably different from, the spider featured in the program.[7]. Where It Lives: Old growth trees or old building in Sri Lanka and India. While the Goliath birdeater is the most massive spider, the giant huntsman (Heteropoda maxima) tends to have longer legs and a bigger appearance. [3] Should Mycterops, Megarachne and Woodwardopterus represent the same animal, the name taking priority would be Mycterops as it was named first, in 1886.[11]. As its name implies, this spider sometimes eats birds. This species is found in the coastal rainforests of Surinam, Guyana and French Guiana, but isolated specimens have also been reported from Venezuela and Brazil. [4], In comparison to the comparatively warm climate of the earlier parts of the Carboniferous, the Late Carboniferous was relatively cold globally. This spider constructs its den within the shifting sand, but comes out to party at night. Otto - Longest human tunnel travelled through by a skateboarding dog, Ashrita Furman - Most Guinness World Records titles held. Despite only two specimens having been recovered, Megarachne represents the most complete eurypterid discovered in Carboniferous deposits in South America so far. Most large spiders are relatively nonvenomous. Body length: 280 mm, Weight: 50 g, lifespan: 10 years, discovered: 1804. Where It Lives: In the wild, this species lives in the forests of Brazil. This climate change likely occurred during the Middle Carboniferous due to falling CO2 levels in the atmosphere and high oxygen levels.

Where It Lives: In burrows in the rainforests and swamps of northern South America. before the middle) carapace, seen prominently in Megarachne, does not occur in Woodwardopterus. The actual identity of the genus, as a eurypterid, was only discovered well into production and by then it was far too late to update the reconstructions. [1], Megarachne was part of the stylonurine suborder, a relatively rare clade of eurypterids. Its scientific name, Poecilotheria, translates from Greek to mean "spotted wild beast." The spread of the ice sheets also affected sea levels, which would rise and fall throughout the period. Males have longer legs than females, but females weigh more (over 100 grams). Wild black camel spider hunting at night in Morocco. [10] A morphological comparison with other eurypterids indicated that Megarachne most closely resembled another large Permo-Carboniferous eurypterid, the mycteroptid Woodwardopterus scabrosus which is known only from a single specimen. Within the stylonurines, Megarachne is a member of the superfamily Mycteropoidea and its constituent family Mycteropidae, which includes the close relatives Woodwardopterus and Mycterops. You can do the math and puzzle that one out. Results", "The true identity of the supposed giant fossil spider Megarachne – 1.
