Gilvossius

Gilvossius is a genus of thalassinidean crustacean erected in 1992 from former members of the genus Callianassa. It is distinguished from Callianassa by the rounded, rather than squarish telson, and by the absence of the first two pleopods in males. The genus contains the following species:Gilvossius arguinensis Sakai, Türkay, Beuck & Freiwald, 2015 Gilvossius candidus (Olivi, 1792) Gilvossius convexus (de Saint Laurent & Le Loeuff, 1979) Gilvossius fredericqae Felder & Robles, 2020 Gilvossius howellorum Felder & Robles, 2020 Gilvossius persicus (Sakai, 2005) Gilvossius rotundicaudatus (Stebbing, 1902) Gilvossius setimanus (De Kay, 1844) Gilvossius tyrrhenus (Petagna, 1792) Gilvossius whitei (Sakai, 1999)SynonymsGilvossius bouvieri (Nobili, 1904) accepted as Paratrypaea bouvieri (Nobili, 1904) Gilvossius brachytelson (Sakai, 2002) accepted as Cheramoides brachytelson (Sakai, 2002) Gilvossius chichijimaensis Sakai, 2015 accepted as Paratrypaea chichijimaensis (Sakai, 2015) Gilvossius diaphorus (Le Loeuff & Intes, 1975) accepted as Callianassa diaphora Le Loeuff & Intes, 1974 Gilvossius gravieri (Nobili, 1906) accepted as Paratrypaea bouvieri (Nobili, 1904) Gilvossius marchali (Le Loeuff & Intes, 1974) accepted as Callianassa marchali Le Loeuff & Intes, 1974 Gilvossius pacificus (Guzmán & Thatje, 2003) accepted as Neotrypaea pacifica (Guzmán & Thatje, 2003) Gilvossius tyrrhena (Petagna, 1792) accepted as Gilvossius tyrrhenus (Petagna, 1792) Gilvossius uncinatus (H.

Time the record covers

At most 4.5 million years on record.

The one occurrence read is dated to somewhere between 20.45 Mya and 15.98 Mya, which is a dating window rather than a span.

1 occurrence of Gilvossius on record, most of them in the Miocene. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.

When

1 occurrences

These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.
